Does R support [:punct:] in regexps?

Hello does R support [:punct:] in regular expressions?  I am trying to
strip all regular expressions for a vector of strings.

It does, but remember that the [] chars are part of the character class; 
you need extra [] brackets around the whole thing, and you don't want 
the slash delimiters:

 > x <- c("yoda-yoda","billy!")
 > gsub("[[:punct:]]","",x)
[1] "yodayoda" "billy"

x <- c("yoda-yoda","billy!")
gsub("/[:punct:]/","",x)

[1] "yoda-yoda" "billy!"

Thanks

Dan
