I would be incredibly grateful to anyone who'll help me translate some SAS code into R code. Say for example that I have a dataset named "dat1" that includes five variables: wshed, site, species, bda, and sla. I can calculate with the following SAS code the mean, CV, se, and number of observations of "bda" and "sla" for each combination of "wshed," "species," and "site," restricting the species considered to only three of...

...a Windows 2000 machine. I've plotted the results of an MDS run labeled by a numerical ID, and color coded by a group code: plot(cv.mds.spr$points, type="n", main="Non-Metric Multidimensional Scaling of SprRun CV Watersheds") text(cv.mds.spr$points, labels = as.character(cv.wshed.id.spr), col = codes(cv.wshed.grp), cex=.75) Question is, how do I get the legend to match the color codes? I have tried different permutations of the following: leg.txt <- c("LSSJ.NS","LSSJ.SS","US.RD","US.SF") # the groups in cv.wshed.grp legend(-6....

I'm plotting the following (stripped of inessentials) xyplot(sd ~ distance | wshed,data=sdvar.df,scales=list(x=list (log=TRUE),y=list(log=TRUE))) sdvar.df is a data frame, sd and distance are numeric, wshed is an ordered factor trying to replicate the action of log="xy" in plot() The plot works fine but the axis values at the ticks are in scientific notation,...
