Is it possible to have a multi-line comments in R? [duplicate]

Answer 1

R Studio (and Eclipse + StatET): Highlight the text and use CTRL+SHIFT+C to comment multiple lines in Windows. Or, command+SHIFT+C in OS-X.

Answer 2

CTRL+SHIFT+C in Eclipse + StatET and Rstudio.

Answer 3

No multi-line comments in R as of version 2.12 and unlikely to change. In most environments, you can comment blocks by highlighting and toggle-comment. In emacs, this is 'M-x ;'.

Answer 4

Unfortunately, there is still no multi-line commenting in R.

If your text editor supports column-mode, then use it to add a bunch of #s at once. If you use UltraEdit, Alt+c will put you in column mode.

Answer 5

if(FALSE) {
...
}

precludes multiple lines from being executed. However, these lines still have to be syntactically correct, i.e., can't be comments in the proper sense. Still helpful for some cases though.

Answer 6

Put the following into your ~/.Rprofile file:

exclude <-  function(blah) {
    "excluded block"
}

Now, you can exclude blocks like follows:

stuffiwant

exclude({
    stuffidontwant
    morestuffidontwant
})
