[R] Is this a bug?
I have found a strange "ifelse" behaviour (I think)
This works:
> ifelse(T,1+1,1+2)
[1] 2
> ifelse(F,1+1,1+2)
[1] 3
Maybe I missed something about R internals, but why
> ifelse(T,print("hello"),print("goodbye"))
[1] "hello"
[1] "hello"
> ifelse(F,print("hello"),print("goodbye"))
[1] "goodbye"
[1] "goodbye"
values are returned two times? I'm not sure: if it's a bug I'll post it
immediately
Thank You
Luca

[R] r.lang for "highlight" software
Dear helpeRs, I apologies if I'll go OT, but I would like to know if someone has yet scripted an "R language definition file" for "highlight" (software for syntax highlight, webpage at http://www.andre-simon.de/ ) better than default one which come with installation (on my Debian it's /usr/share/highlight/langDefs/r.lang). If yes, is it accessable via web?
