[R] replacing period with a space

[Dimitri Liakhovitski]

Dear R-ers!

I have x as a variable in a data frame x.

x<-data.frame(x=c("aa.bb","cc.dd.ee"))
x$x<-as.character(x$x)
x

I am sorry for such a simple question - but how can I replace all
periods in x$x with spaces?

sub('.', ' ', x$x) - removes all letters to the left of each period...

Thanks a lot for your advice!
