如何连接两个字符串？

Question

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

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

My goal is to concatenate the two values in "tmp" to one string:

tmp_new = "GAD,AB"

Which function can do this for me?

Answer 1

> tmp = paste("GAD", "AB", sep = ",")
> tmp
[1] "GAD,AB"

I found this from Google by searching for R concatenate strings: http://stat.ethz.ch/R-manual/R-patched/library/base/html/paste.html
