1. Please don't post in HTML (see posting guide). 2. What do you mean by "extract?"
3. Your qiestion sounds very basic. Have you read "An Introduction to R" or other online R tutorial? If not please do so before posting further. All of R's file input functions allow you to specify the directory path and/or filename, so if I understand you correctly, it's just a matter of giving them to the appropriate function in some sort of loop. e.g. something like alldat <- lapply(filenameList, function(x)InputFunction(x,...)) 4. If you need something fancier than is described in the tutorials, consult the "R data Import/Export manual," please. -- Bert On Fri, Nov 8, 2013 at 9:33 AM, Zilefac Elvis <zilefacel...@yahoo.com> wrote: > Hi, > I have 300 .txt files in a directory.
