How do concat a vector of character in R?

I tried using the paste command but it returns the same 开发者_StackOverflow社区vector?

x = c("a","b","c")
y = paste(x)
y
[1] "a" "b" "c"
length(y)
[1] 3

I want a single character of "abc"

The collapse="" options is your friend:

> x <- c("a", "b", "c")
> paste(x, collapse="")
[1] "abc"

[ There is still no rstats tag here. ]
