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\"

Alternatively, if your objective is to output directly to a file or stdout, you can use cat:

cat(s1, s2, sep=", ")
