Hi,
   I looked in the language definition and was surprised. Is there
really no multi-line/block comment defined in R?

   I wanted to comment out 20 lines that I'm moving to a function but
didn't want to delete them. Is there no defined way to get around
using a # on each of the 20 lines?

Thanks,
Mark

Hi,

This issue has come up before, and as far as I know there is no multiline comment. However, there are a few ways of commenting out larges pieces of code.

- Use a good text editor, Kate (KDE) allows you to select the 20 lines and press Ctrl-D to comment them all at once.
- Use a setup like:
if(FALSE) {
line1
...
line20
}

And set FALSE to TRUE if you want to let the code be executed.

These are probably not the only ones, but this is what I could think of right now.

cheers and good luck,
Paul
