Dear List-mates, I have been trying to set up a 4x8 trellis plot (that is, 4 columns, 8 rows), and would like to have the axis limits set based on the data range of rows (for ylim) and columns (for xlim). I've been using the call:
foo<-xyplot(y~x|Epoch+Subject, type=c("l","r"), par.strip.text=list(cex=0.5), ...) and updating to see different effects of scale adjustments, & etc. foo<-update(foo, scale=list(relation="sliced")) #etc. I can have each panel with its own limits using relation="free", limits wide enough to accommodate the whole data range with "same" or the limits of the widest panel for all panels with "split". I have not, however, figured out a way to have the limits for x & y grouped by their column or row. Documentation points to 3 alternate ways of trying to set stuff in panels. (1) a prepanel function, (2) using scales, or (3) focusing in on each panel individually & changing some setting. I've played around with accessing different panels individually with foo[column, row], and using a list to determine which get displayed (instead of using skip because I can't get skip to work). Would I be able to set the xlim values in a similar way? foo[1,]$ylim<-newvalues to set a whole columns ylims (e.g by data range of y in conditioning variable 2 (subject in my case)) and foo[,1]$xlim<-newvalues to get a whole rows xlims by the data range of x in each level of conditioning variable 1 (Epoch in my formula))? If so, what attribute should I access, and if not what would you recommend? I've been reading posts, working examples in Venables & Ripley 4th Ed., and experimenting with different things for the last 4 days. I'm still not used to the lattice terminology, so I could have easily miss interpreted what something was meant for (example- prepanel makes no sense to me yet). Conversely, I got a lot farther, a lot faster, using Lattice than I did using plot or ts.plot. In addition to a much shorter list of attributes that don't make sense to me yet than otherwise, I have been really tickled with the Lattice package. Thanks in advance for your feedback.
