Re: [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
