Replace all double spaces with single spaces in string

原文 2014-04-11 15:02:14 0 1 regex/ r/ whitespace/ gsub

I would like to reduce all spaces longer than a single space in a string to a single space.

foo(" 1   2    3     4                 5 ")
[1] " 1 2 3 4 5 "

That would work:

gsub(' +',' ',foo)

:)
