[R] Stratifying data with xyplot

Hi, I am a big user/fan of the lattice package for plotting. As far as I know, lattice only offers one method to stratify data within a xyplot panel, using the groups arguments. A contrario, the ggplot package allow users to use different variables for coloring, setting the symbols, the line

Re: [R] Q re: logical indexing with is.na

logical indexing requires the logical index to be of the same length as the vector being indexed. If it is not, then the index is wrapped to be of sufficient length. The result on line 3 is y[c(TRUE, TRUE, FALSE, TRUE)] where the last TRUE was originally the first component of !is.na(y[1:3]) Gra

Re: [R] About wilcox test

First, I'm pretty sure this is a statistics question, not an R question. But you're asserting there is a difference in the data. The statistical test is telling you that this apparent difference is within the range of chance variation. There's not a contradiction there, unless you mean there is
