Hi, I have a string "InTrouble" and want to extract, say, the first two characters: "In" or the last three: "blee" or the 3rd, 4th, and 5th: "Trou" Is there an easy way of doing this quickly with regular expressions in gsub, grep or similar?
Hi Gon?alo, You could always try: Im<-"InTrouble" paste(unlist(strsplit(Im,""))[c(7,4,1,2,9,8,5,6,3)],collapse="") Jim
