Date: Wed, 31 May 2000 22:27:06 +1200 From: Ko-Kang Wang <Ko-Kang at xtra.co.nz> Just out of curiousity, why is it I can't do multiple commenting in R. I have to type # in front of each line (well, it's true). If there are 20 or more lines it becomes a bit annoying. In SAS there is /* blah blah blah */, which comments out an entire block. Java and C++ have the similar feature too. Will it be possible to put this feature in R in the future?
There are a couple of conventions here. C uses /* blah blah blah */,
but as I understand it // rest of line is preferred in C++. Indeed,
there is some tendency for C++ programmers to find it convenient in C,
and gcc lets it be used. Perl uses # rest of line and TeX (and Rd) %
rest of line, and Visual Basic ' rest of line and ...
With a good code editor none of these are any problem. There is no
reason to write many lines of comments in R code: that's what the .Rd
file is for. And if you want to temporarily delete a block,
if(0) { ... } will work, as indeed will temporarily deleting in an editor.
