You don't need a loop:
filename <- sub("([^.]+)(\\..+)", "\\1", dir("c:/data/"))

PS: Just to get your loop working (you don't want to do it that way!):
filename <- NULL
for (i in dir("c:/data/")){
filename <- c(filename,sub("([^.]+)(\\..+)","\\1", i))______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
