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

Given the matrix, tmp, that you created:

paste(tmp[1,], collapse = ",")

I assume there is some reason why you're creating a matrix using cbind, as opposed to simply:

tmp <- "GAD,AB"
