Hi, I wonder whether there is a wild-card character in R. For example, I use ReadAffy("file1.txt", "file2.txt") to read a subset of files in a directory. Can I use a wild-card character in this command like ReadAffy("file*.txt") ? Thanks a lot. Po

Use ReadAffy(dir(pattern="file*.txt")) and see ? dir Cheers ---------------------------------------- Wolfgang Huber Division of Molecular Genome Analysis German Cancer Research Center Heidelberg, Germany ----------------------------------------
