How can two strings be concatenated?

Question

How can I concatenate (merge, combine) two values? For example I have:

tmp = cbind(\"GAD\", \"AB\")
tmp
#      [,1]  [,2]
# [1,] \"GAD\" \"AB\"

Answer 1

Another non-paste answer:

x <- capture.output(cat(data, sep = ","))
x
[1] "GAD,AB"

Where

 data <- c("GAD", "AB")
