Yes there is.

Subject: [R] Combining the components of a character vector
Dear Help,
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"
The following function combines the character vector into a string in
the
way that I want, but it seems somewhat inelegant.
paste.vector <- function(x, ...) {
output <- NULL
for (i in 1:length(x)) output <- paste(output, x[i], ...)
output } #end of function definition
paste.vector(x)
[1] " Bob loves Sally"
Is there a more natural (no loop) way to do this in R?
