Regular expression in R to remove the part of a string after the last space

Question

I would like to have a gsub expression in R to remove everything in a string that occurs after the last space. E.g. string="Da Silva UF" should return me "Da Silva". Any thoughts?

Answer 1

Using $ anchor:

> string = "Da Silva UF"
> gsub(" [^ ]*$", "", string)
[1] "Da Silva"
