Hello
Yes, I am sure you are right. I guessed the intended question was not so specific. I have always thought of spaces and blanks as the same thing. And use "white space" for a more general catch all description for tabs etc. Is "white space" and "spaces" the same thing?

Hint 1: there is no need to globally substitute patterns anchored at the end: they can only match in one place. There is also no need to substitute "" for "". Hint 2: 'blank characters' and 'spaces' are not the same thing. [:blank:] seems the relevant character class, so sub("[[:blank:]]+$", "", x) seems an accurate answer to the question asked (which might not be the question intended).

But that removes *spaces* and not *blanks*, according to the help page (and the actual code -- in fact it removes only ASCII space characters and not others such as nbspace). > Regards > > JS > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > On Behalf Of jim holtman > Sent: 27 June 2008 10:27 > To: juli pausas > Cc: R-help > Subject: Re: [R] removing blanks from a string > > Is this what you want: > >> x <- c("hola ", "Yes ", "hello ") >> gsub(" *$", "", x) > [1] "hola" "Yes" "hello" >> >> > > > On Fri, Jun 27, 2008 at 4:34 AM, juli pausas <[EMAIL PROTECTED]> wrote: >> Hi >> Is there a way to remove blank characters from the end of strings in a > >> vector?
