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