There are many great things about the open nature but it also leads to a very diverse experience, depending on which subreddit and thread you visit. Discussions range from asinine to profound, and casual visitors are often quick to generali

It's amazing to think that R (or S) had data frames since the 70s and only now are other languages implementing them. There are some quirks of course, and pandas introduced some convenient features. But the R community has also provide

How about PyCharm or Eclipse+PyDev (I've personally heard more praise for the former)? I use emacs and ess or python-mode so can't comment on the IDEs too much but being able to use the same platform for both has been convenient f

and if you overwrite variables like "c", you can always invoke the original concatenation function as "base::c".

I agree, I've read other gripes about R function documentation but it's one of the better ones for community software. Python's documentation seems focused on implementation from a programmer's perspective, but often not

Isn't this the conventional way of converting variables which have been coerced to their numeric representations back to time/date classes?

Hi Hadley, yes for instance > as.chron("1970-01-01")+unclass(as.chron("2001-04-01")) [1] 04/01/01 > as.POSIXct("1970-01-01","EST")+unclass(as.POSIXct("2014-06-01","EST&q

I understood that at least a part of the larger programming community felt that the non-concurrent GC was limiting its future growth and shopped elsewhere for a production language.

In the R Help Desk 2004 ( http://www.r-project.org/doc/Rnews/Rnews_2004-1.pdf ), Gabor Grothendieck recommends chron over POSIXct classes on account of the time zone conversions which occur when the tz attribute of

Does lubridate solve the unintended timezone conversions of POSIXct classes?

I understand there have been studies showing people don't estimate angles as well as linear distances but people go too far out of their way to avoid pie charts when parts within whole data is shown. The 1D mosaic plot is effectively a

Can't you just create an alias for `emacs -nw -Q` or `emacsclient -nw` when you want to open an instance in a terminal?

I find it hard to believe that six years could solidify a culture of monolingualism; what about languages other than German?

The syncing with LaTeX sounds nice. What's imagemagick for? If you can copy text I guess it doesn't convert to png like emacs does now?

Is rhdf5 the best library? I understand there is ncdf4 and h5r, and rgdal. I understood that R support for HDF5 was limited so I have not used R much for this purpose.

Again, if you remember to include options(stringsAsFactors=FALSE) at the top of your scripts, they are transferable. With other R neophytes who only run code that I write, I tell them to run cat("options(stringsAsFactors=FALSE)\n"

This is really well-written. I was skeptical about the title's claim but truly, the author defines what first-class citizens mean and a wide range of cases where the behavior is inconsistent. I have gotten used to its behavior but only

They've agreed to do this site-wide at the Mayo Clinic. https://stat.ethz.ch/pipermail/r-help/2007-February/125438.h... I have adopted this approach as well, and for all the scripts I distribute I set op

Right, it's the "pretty much" part that's a little disturbing. Would be nice to know why this caveat is always thrown around.

I think the most important thing would be for the community to understand what ports and what doesn't port from the elisp version that everyone uses- until then I don't think many will be able to make an informed decision regardin

Wow, I haven't seen the licensing model to use a language in a while. Many researchers are migrating away from MATLAB for that reason, and new projects are often not initiated in MATLAB unless it incorporates legacy code. How's th

I am a strong advocate of this method. However, I have to issue a statement of warning that when an idea doesn't pan out like written out, people will go to great lengths to fulfill their agenda (e.g., put undue pressure on their stude
