Apologies if this is in (one of the many) manuals somewhere... Trying to switch to R from other stats programs.
Basically, I have a large data table I've dumped from a DB, some of the values which are nulls '-' which I've converted to zeros. I've read it in using read.table fine. I want R to ignore the zero values when graphing or doing various other calculations. Is there a way to do this ? I did try to use NA but kept getting errors that x must be numeric. thanks in advance, Daryl. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
