> I just don't see a better alternative Julia?
The biggest Julia cheerleaders gave up years ago. That doesn't mean the language is dead but it's not a great sign for a niche lang

No, you are wrong. R is terrible , and especially so for non-professional programmers, and it is an absolute disaster for the applications where it routinely gets used, namely statistics for scientific applications. The reason is its strong tendency to fail silently (and, with RStudio, to frequently keep going even when it does fail.) As a result, people get garbage results without realizing , and if they're unlucky,…
R is fundamentally flawed. It tries to merge two highly conflicting goals: a productive analytics environment and a programming language. To do the first really well means automating away many of the issues that would crop up in the second allowing R to 'just work'. Because of that nothing beats R for getting to an answer as fast as possible (not even Python) at the cost of making it more difficult to productionise a…

While I kind of want to agree with you, I just don't see a better alternative. Do you really want biochemists to have to deal with the horrors of C compilation? In production code I'm very glad my makefile tells clang to fail on absolutely anything, but is that the best we can do? Other commenters have pointed out ways to avoid dangerous things like integer division, but if you think R is hostile then please offer a…
I have very quick flows for data processing: load data, make long form, add meta data as categories, plot many things with seaborn one-liners. I use Jupyter lab and treat it Like a full lab notebook, including headers, introduction, conclusion, discussion. Works very wel for me.
There are a bunch of odd non-standard syntax choices in this tutorial. For example, the author ends statements with semicolons. R does allow equal sign assignment (although style guides prefer the stupid arrow syntax). The author mentions Bioconductorm the... second biggest package repository for the language? I clicked because I was a programmer for 15 years before I used R, and I have subsequently developed and shi…
the "stupid arrow syntax" is not nearly so stupid, and I speak here as a 10+ year Python developer, as the misuse of the equal sign that every C-style language seems to think is ok. The = sign meant something long before computer programming, and it is something the developer community ought to be ashamed of that it is being used for "change this thing to that". /rant
?- a = a.
true.
?- a = b.
false.
?- A = a.
A = a.
?- A = a, A = b.
false.
?- A = a, A = B.
A = B, B = a.
?- A == B.
false.
?- A = B, A == B.
A = B.
(hint: "=" is not assignment, neither is it equality and "==" is just a stricter version thereof).

Ubuntu doesn't ship with pip or virtualenv. In fact it ships with a version of Python where the built-in equivalent to virtualenv, pyvenv, is explicitly disabled. So you have to install extra Python packages, as root. You have to have that Python experience that guides you to install as few of them as you can, just enough so you can get started with a virtualenv, so you don't end up relying on your system Python envi…
That sounds like a major problem with Ubuntu, rather than with Python or pip. On Windows, meanwhile, the standard Python installer gets all this set up properly in like three clicks. Better yet, because it installs per-user by default, "pip install" just works. And if you still choose to install it globally, it will fail, but it will tell you exactly what you need to do to make it work: Could not install packages due…
HN is predisposed to hate R because everyone here is coming from a "real" programming context. Their concerns are generally valid, but they should keep in mind a lot of people using do not have a software development background and do not care that the language is not elegantly designed: they just want to get analytical work done. In that respect, R is far, far superior to Python. Even something as simple as installi…
> Even something as simple as installing a library is a conceptual leap for these people (why wouldn't the software just come with everything needed to work?). > Have you ever tried explaining the various python package and environment management options to someone with a background in Excel/SQL? I don't understand the difficulty I've often seen voiced against this. Why would a newbie or someone who just wants to get…
Except when it isn't. For instance, because some wheel fails to build because you're lacking the VC++ redistributable (or it's not where pip thinks it should be):

Note that this is just one case where I was trying to install one particular package. I got a couple more examples like this in my installation diary, notably one when I tried to install matplotlib, this time on Windows Subystem for Linux, a.k.a. Ubuntu, and hit a conda bug that meant I had to use an older version of QT until upstream fixed it and other fun times like that.

>>Have you ever tried explaining the various python package and environment management options to someone with a background in Excel/SQL? Yes, well, from the outside it doesn't seem like Python programmers have any better grasp of those either.
