Extracting arithmetic mean for specific values from multiple .txt-files
Dear Mr. Holtman and especially dear Rui, thank you VERY much. You helped me a lot!

Thanks a lot again! -- View this message in context: http://r.789695.n4.nabble.com/Extracting-arithmetic-mean-for-specific-values-from-multiple-txt-files-tp4635809p4636265.html Sent from the R help mailing list archive at Nabble.com.
