[R] Concatenating one character vector into one string

We need both sep and collapse to deal with situations where we are
pasting two character vectors and also where we are pasting just one.
paste(c("T","i","o","s"), c("his ", "s ", "ne ",
"entence."),sep="",collapse="")

Rainer,
This works: paste(x, sep="", collapse="")
I would have thought this 'paste(x) would work, but it didn't.
Perhaps someone else can tell us why we need collapse="". What would
break if the default was collapse="" instead of collapse=NULL?
Thanks,
Roger

Hi
I am sure this is simple - but how can I convert one charecter vector
into one string?
example:
x <- c("This ", "is ", "one ", "sentence.")
should become
"This is one entence"
Thanks
Rainer
