Is there any standard logging package for R? [closed]
(7 answers)
Closed 8 years ago.
Which logging package would you recommend for R? I am aware there are several packages available but would like to know which one is considered the best. Specifically, here is what I am looking for:
multiple logging level
built-in support for rotating log file
fast (should not slow down too much existing code)
painless to setup (not too much boilerplate code)
For simple logging, evaluate ?sink

%>% key binding / keyboard shortcut in Rstudio
(5 answers)
Closed 5 years ago.
It's great in RStudio to have already a key short-cut for <-, which is ALT+-.
Wouldn't it be also great to have also a short-cut for %>%, which is possibly the second most frequent key sequence (after <-) that R programmers type?
Or maybe there is already one?
If you want to solve this in rstudio you can create an addin and reference a custom shortcut to your addin. Here is the reference page which will guide you through the process: https://rstudio.github.io/rstudioaddins/

Show names of everything in a package

My question is similar to this question and in fact, is answered there. But because it took me a lot effort to find the answer there. I preferred to create a new more organized one and answer it myself.Now the question is:
If I want to see all methods, dataframes, etc of a package that I only know its name, what should I do to access them very easily?
Just enter this code:
help(package='PACKAGENAME', help_type='html')
for example to see all you have in the R basic package, stats:
help(package='stats',help_type='html')

Figure out what version of R a function was introduced in
(2 answers)
Closed 9 years ago.
Is there a way to determine rather easily when an R function was added (what version number). Take for instance when were:
paste0 and browseVignettes added?
I'm not really looking for when these were added but a way to see when they were added.
Converting my comment to an answer as requested:
You can use the news() function
news(grepl("paste0", Text))
Go here: http://cran.r-project.org/src/base/NEWS.html
paste0 was in 2.15.0 and browseVignettes was 2.13.0 but it doesn't seem to mention browseVignettes.

I want to write my own JIT compiler for CIL and I don't want use library to generate compiler. Do you have any tutorial, ebook or example?
Here ya go, this should be a pretty good resource.
Some of them are ruby-specific, but there are plenty that aren't, as well.
You could start with Rotor. There is a free book accompanying the code base as well.
