Could you be a bit more precisely?
If you are dealing with two fix strings then you can write
ifelse(theString == "AAAAA BBBBB", "AAAAA-BBBBB", "AAAAAA")
if not, one could find a regexp to solve that problem, but one could
also use gsub in a cascade:
gsub('regexp1', 'replace1', gsub('regexp2', 'replace2', theString) )
