I feel like CRAN should be used for packages that are expressly made for others to use, and with effort put in to the documentation and vignettes.
If you’re making a package for a small team or aren’t pushing it to a large audience then just keep it on a GitHub repository. It is almost as easy to install from GitHub with devtools as it is to install.packages().
Exactly. I made a small package for my lab and just put it on GitHub. My guess is that many academics don't know that you can install packages from other sources than cran
People would typically choose based on CRAN TaskViews or follow conventional methodologies, but what I notice from this is that R is truly a language used only by those who use it. And the people who use it are usually master's students or professors; it's rarely used at the undergraduate level. So even those with that level of academic background and training must have had their own implementation roadblocks. Could that be why the use of R has exploded with the help of AI? Looking at this, I think it's fair to understand that even domain experts found programming difficult. Seeing this, can we really say that AI is always bad? For some people, it has become both the hands and a voice for their words.
A considerable amount of work for grad students is answering the question: "How the f#$% do I get this code to compile and run"
Some other researcher, often with limited skills in your native tongue, even more limited skills in software development best practices, wrote some code for a paper between 5 and 50 years ago and your PI has told you to use that code and some OTHER code together at the same time to validate some experiment he wants you to do.
In the past you would take days/weeks/months to get this to work, but with an LLM?
I'm envious of the grad students of today for the amount of nonsense which is bypassable.
There is some great stuff in R but from a software engineering level I'd much rather data scientists work in Python.
At risk of sounding like ChatGPT, it's not an R thing, it's a general thing. Turn [showdead] on in your profile and see how Show HN is flooded with AI slop projects and we all know GitHub is drowning in it.
I also think Python is a bit better. (Though, unlike you, my programming skills are directly tied to my livelihood, so it benefits me if one language can cover as much ground as possible. Being locked into a specific domain just narrows the number of jobs I can take on.) You're not wrong, but it makes me pretty sad that all my homepage submissions are marked as 'showdead' and no one ever sees them. Maybe my submissions would look like rubbish by your standards. But looking at it that way, there's also the gap between what people expect and what the site's filters decide.
You're right. I think I overstated it. Since English isn't my native language, I might have used some stronger words than intended. Thank you for pointing that out
Programming is a lot easier than statistics bc it’s deterministic, whereas statistics is stochastic (that extends and encompasses deterministic functions).
AI speeds up learning, so I bet that’s what you’re noticing with R.
As an aside, the best programmers these days are probabilistic programmers (who write stochastic functions). Our languages are Stan and PyMC. Both can be called by Python or R, and AI writes all of them extremely well. So it seems to me that the underlying language matters less than ever.
I partially agree, but I also differ on some points. The part I agree with is that probabilistic programming is difficult and that advanced programmers tend to enjoy it. Where I differ is on the claim that programming is deterministic. At the script level, programming is deterministic and sequential, but once it crosses a certain threshold, it becomes absolutely probabilistic. That's because latency, locks, and asynchronous communication start to intervene. If programming were Non deterministic , C's undefined behavior wouldn't exist; everyone would have prevented it.
R these days mostly uses the tidyverse, which feels like a variant of DOP (Data-Oriented Programming). It's a kind of data flow, so it's different from typical OOP. I also occasionally work with statisticians (being a freelancer, ETL work is more common than you'd think), and I know what you mean by Stan and PyMC. I know they're powerful tools for Bayesian statistics and multilevel modeling. I know the basic syntax and examples, but I wouldn't say I know them well. My level is mainly focused on the scientists who hire me, and those tools still don't come up often in my country.
That said, I think we differ on the bigger picture because academic code isn't everything. Academic code is typically algorithm‑centric, like LeetCode problems, but most production work revolves around code hygiene and responsibility (algorithms are usually already established ones). Anyway, that's not the main point. What you said is mostly correct, but my focus was on something else: even people who studied at that level can be surprisingly clumsy at expressing themselves through programming. Regardless, thanks for your input, and I agree that AI is good at programming. But using a programming language generally means understanding its tradeoffs, and R is tricky in that regard since it feels like a mix of OOP and DOP variants
Programming isn’t even a field in the same way as prob&stats. Computer science does in fact have non-deterministic sub fields such as information theory.
There’ll always be boundary tending, true. Only a portion of CS deals with stochastic functions though, whereas all of statistics is stochastic. That makes a big difference, bc the world is complex.
Information theory doesn’t even incorporate utility.
CRAN has very different social structures and culture than other languages' package repos. CRAN _will_ pull your package from the repository if you fail to play nice with all packages, for example. This is evidently controversial, but it's accepted practice and one possible explanation for why CRAN feels more cohesive than NPM or PyPI.
CRAN is not a conventional package repo. Its audience is not really people who care about programming or software. It is a means to an end for them and slop is perfectly fine. The language itself is also very simple and has defaults that people don't even bother changing. For example the default output file name. It doesn't ask for an output file name when you save output.
As a result of the above, it is full of packages that come with associated datasets right in the package itself. Packages with a tiny script and gigabytes of data. Or perhaps just the data without any actual code.
CRAN is a weird universe, but not (just) for the reasons you mention. CRAN is still heavily human maintained which means that there's a high chance that an actual human will look at your packages (at least for your first package). This imposes a considerably higher barrier to entry than most package repos, and hence I suspect CRAN actually has a considerably lower percentage of slop.
The fact that there is a human (and one with expertise in R) reviewing each incoming package makes pure vibe coded slop much, much harder to get approved.
OK you are right but that is selective for an "overview". The attention to documentation has always been outstanding for substantial packages. The culture is to make many repetitive steps into one liner "magic" that sometimes is very very useful; lastly, the completeness of advanced statistical methods in standard libraries is real. ps- I do not like the R language at all myself, but to be fair there are reasons it is widely used in higher ed.
I only dipped into it a little bit while helping out a friend. It looked weird to me but I didn't mean to sound so negative. Sorry. I am sure it does get the job done or people wouldn't be using neither R nor the CRAN.
First, usage: Using R for our undergrads in time of LLMs is brilliant. ChatGPT slops out working code for their needs. Not pretty but works better that in 2022.
Second, development: Mastering R is hard, because its kalkül. Tidyverse mediates some of it, but still. This is the perfect breeding ground for slopification. Lets see.
Third, errata: I would love to know the percentage of science built on R to this day. I mean insights and analysis supported by it and it vast packages. What if somewhere, deep down in the stack there is an ancient bug that dented all of this? I think AI might help us here, or review slop will negate this?
>What if somewhere, deep down in the stack there is an ancient bug that dented all of this?
Science is built on libraries with experience, that have been validated extensively against reality. Code often written by people who have retired and died because that exact same code has been validated and pinned to reality for decades. It is of course possible that a load bearing bug survives for a long time conspiring with an incorrect model of reality to give validated results, but wide use tends to eliminate these things.
We have too many videos (since creating one is so easy), too many music (since recording it is so easy), too many books (since publishing an e-book is so easy). Now the same story happens again, for software. But this time it causes more troubles...
Frankly the bigger problem is an over reliance among R instructors on the tidyverse, an ever-expanding ecosystem of redundant functions and anti-patterns. They’re teaching new R users that everything can be solved with yet another package import and skipping over teaching them how to use the already powerful and intuitive base packages.
I’m not saying it doesn’t have flaws, but the tidyverse is still the most coherent and functional ML/stat computing ecosystem I’ve ever used. R packages outside of the tidyverse can get pretty gnarly. Even the R stdlib is usually considered to be inconsistent and riddled with legacy cruft.
I’m a big fan of Polars. It’s really fast and memory efficient. With the lazy streaming functionality, I’ve been able to easily process 1 Tb+ data on a single machine (you do have to be careful to not do any operation that would cause the whole DF to materialize in that case).
It’s certainly miles better than Pandas, which has a terrible API in addition to being comically inefficient. In my group, we generally use it for any new work, and have also swapped out pandas for polars in critical spots of our existing code - the latter giving a huge benefit relative to the amount of work it took.
I largely agree with you on SQL being the common denominator, but there are some things that are just awkward in SQL, and much easier to do in Python or other general purpose language.
I couldn’t disagree more. The base packages are a complete mess. If R was subset to only the tidyverse 5 years ago then it wouldn’t have lost so much ground to Python in nearly all fields.
Posit is obviously the only organization with the pull to do that, and I feel like they got pulled in 10 directions during the move to AI and trying to also support Python. R Shiny is dead too which sucks because reflex.dev just copied them and ate their lunch in 3 months.
The proof is in the pudding. Every single grad student of mine that was brought up on the tidyverse produces gigantic R markdown files with 20 imports to accomplish something that would be shorter and much much easier to understand (and review!) with a base package or with one of a small number of packages (box, data.table) designed by people who understand programming.
Not to mention the ridiculous styling/formatting of most tidyverse users, which Wickham and others seem to promote. One of the reasons R has lost ground to other languages recently is that most R code these days is ugly
That was always my struggle w tidyverse vs base mastery.
From the looney tunes cartoon of the road runner vs the coyote, the coyote used tidyverse and the road runner used base R.

The fact that young people are producing sub-optimal code (in terms of whatever optimization criteria you are choosing--here, it sounds like terseness) is not strong evidence that a particular software ecosystem (tidyverse) is flawed. Young people producing bad code is not surprising. They're your grad students, mentor them, and maybe they'll adapt to your ways of thinking. Or not.
> One of the reasons R has lost ground to other languages recently is that most R code these days is ugly
Citation needed, surely. The fact that this article is about an increase in the number of CRAN submissions and pseudo-quantitative indices like the TIOBE index show R's slice of the pie is growing provides evidence to the contrary.
> Young people producing bad code is not surprising. They're your grad students, mentor them, and maybe they'll adapt to your ways of thinking. Or not.
You’re right, mentorship is key and I do my best to suggest better practices. They are often quite happy to find out they can do more with less and can forget having to remember multiple additional syntaxes (looking at you “ggplot2”).
I somewhat understand why R instructors lean towards the tidyverse - Wickham’s group produces a ton of tutorials and workbooks, so it’s easy to just point students there - but it has led to entire cohorts of people producing poor code
Python is just such a good Swiss army knife and it's never a waste to learn: you can do data science and you can do almost anything else. It's the BASIC of the 21st century.
The solution to this problem will be a web of trust featuring a vouching system that auto-closes PRs by default. I already see this being implemented in projects.
One of the things that always reassures me about LLMs is that as well as being trained on languages with reasonably well-designed grammars, they will also have seen lots of examples of good practice in their training set.
Two things that make me wonder if they can possibly turn out good quality R.
Perhaps a true test of AGI will be when you ask it to write an application in R and it refuses for fear of what people might think.
> People I've worked with that used R and manged data / did analysis didn't really seem too concerned with long term maintenance.
Unless you’re the poor schmuck who is given the task of running the code written by the previous analyst, who has probably already left the company. Often it’s easier to just throw something together from scratch and then look for a new job, perpetuating the problem.
At my job I switch between writing analysis code for research projects and writing code for apps. The difference in mindset is so dramatic. In the same way that good software has consistent names and interfaces that are ~useless when you just need the code to run once, research code has its own requirements that are ~useless in software. It's honestly a big challenge to switch back and forth. So I think it just reflects the main skillset of the people who use it (caring is not enough).
Bingo. The typical data scientist has a masters or PhD in a non-CS quantitative field, and has had exactly zero CS or software eng classes. It’s a shame, because once you get over some of the idiosyncrasies, R is a really powerful and flexible functional language.
Conversely, it is the programming language of choice for people who don't assume that their expertise on one domain (data science) translates into expertise in the whole of human knowledge (as we often see among techbros generally and here specifically).
As a working data scientist, I know I am not a computer scientist or a 10x engineer (hell, I am probably a 0.8x engineer), but that's not where my expertise is. My engineer co-workers are 0.01x data scientists, but you won't see me complaining that they don't know the Central Limit Theorem or how to build a causal inference engine.

Is anyone arguing “AI is always bad”? I think the argument is clearly “the negatives outweigh the positives”.

Picking up on some dunning kruger effect here.

The surprising thing to me is that it's taken as long as it has for CRAN to have this problem. As others have said, this is happening everywhere.

This is evidently controversial, but it's accepted practice and one possible explanation for why CRAN feels more cohesive than NPM or PyPI.
I remember the controversies well :) but I guess even their extra gating is starting to creak by the sounds of it.
It's the same on any package index now.

Absolutely correct. CRAN takes down and rejects packages all the time for minor issues and violations of their rules and guidelines. And there are a lot of them: https://cran.r-project.org/doc/manuals/r-release/R-exts.html
The fact that there is a human (and one with expertise in R) reviewing each incoming package makes pure vibe coded slop much, much harder to get approved.

It's certainly quite pleasant to work with...but I would rather use sql for etl, the backend be whatever it needs to be...
The real world data transformations can get gnarly very quickly and sql is the perfect common debiminator compared to dplyr which is still niche...
How do you feel about polars?
I’m a big fan of Polars. It’s really fast and memory efficient. With the lazy streaming functionality, I’ve been able to easily process 1 Tb+ data on a single machine (you do have to be careful to not do any operation that would cause the whole DF to materialize in that case).

Data.table is a masterclass in bad API design. Its lack of success despite its technical merits is entirely of their own doing.

I do wonder if there isn't enough computer science / software engineering that is being taught as part of data science.
