Hi,

In C++, I can use the following construct to choice either of the two
blocks the comment but not both. Depending on whether the number after
"#if" is zero or not, the commented block can be chose. I'm wondering
if such thing is possible in R?

No. The usual advice is to get a real editor that can comment a block of lines all at once.

#if 0
commented with 0
#else
commented with 1
#endif

Peng
