I suspect it will be difficult with dotplot. It is expecting a factor variable for the y-value and appears to be coercing the LHS argument to one. Why not use xyplot if you are plotting numeric by numeric? If you what to add horizontal lines `ala` dotplot you could construct a panel that had the appropriate commands. -- David. > Here's my data: > https://www.dropbox.com/s/egy25cj00rhum40/data.csv > > And here the program code so far: > > df.dose <- read.table("data.csv", sep=",", header=TRUE) > library(lattice); library(latticeExtra) > > useOuterStrips(dotplot(z ~ sample.size | > as.factor(effect.size)*as.factor(true.dose), > groups=as.factor(type), data=df.dose, as.table=TRUE)) > > I'd be glad for any kind of help! > Andres > David Winsemius, MD Alameda, CA, USA ______________________________________________ R-help@r-project.org 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.
