[R] Use of [:alnum:] or . in gsub() etc..

test = c ( AAABBB, CCC ) This works : gsub ( [A-Z], 2, test ) None of these do : gsub ( [A-Z], [:alnum:], test ) gsub ( [A-Z], [[:alnum:]], test ) gsub ( [A-Z], [:alnum:], test ) gsub ( [A-Z], [[:alnum:]], test ) gsub ( [A-Z], ^[:alnum:]$, test ) What am I doing wrong, please ? --
