Sorry - this must be obvious, but i haven't been able to find the answer in the guides i've searched. The examples seem to assume you always want to look at all the data.
I want to be able to filter data in a dataframe before analyzing it. For example, I'd like to plot(a,b) but only include values where b > 1000. I'd also like to be able to do similar filtering before doing other statistical functions. Thanks for your help. ______________________________________________ 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 and provide commented, minimal, self-contained, reproducible code.
