How to concatenate a vector of strings to a string?

paste(c('a','b'),sep='')

[1] "a" "b"

The above command doesn't concatenate the strings in a single string.
I'm wondering what is the correct way to do so.

Remember that paste is vectorised. That behavior is desired:

 > paste('a','b',sep='')
[1] "ab"
 > paste(c('a','b'), c(1,2), sep='')
[1] "a1" "b2"
