Hi Chris, 'gsub' does exactly what you want: gsub(",","",text)
so there is no need for a loop. Btw. your loop assigns a new value to m in each step and you see only the last assignment. you could do something like m <- paste(m,substring(text,i,i+2),sep = "") hth Am 03.02.2011 17:35, schrieb Chris82: > > Hello R users, > > I have a little problem with a for loop. > Below there is an simple example of my problem. > > I want to delet the commas in the character string.
