Combining the components of a character vector

   Suppose I have a character vector.

x <- c("Bob", "loves", "Sally")

I want to combine it into a single string:  "Bob loves Sally" .
paste(x) yields:
paste(x)
[1] "Bob"   "loves" "Sally"

Is there a more natural (no loop) way to do this in R?

paste(x, collapse=" ")
