On the other hand, be glad it isn't a .dbf file and that you are not using dBASE. Ancient history of course, but dBASE used to convert missing data (NAs) into 0s when you weren't looking. If you were extremely unlucky and stuck in the role of autodidact, your success in both noticing and identifying the problem could be a long time coming. In the meantime, your instructors might be numerate, and point out rudely your inability to carry out even simple calculations of averages, or they could be innumerate and happily accept your mistakes as gospel because you included "quantified" results in you paper. Good luck. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
