The multicomp package was replaced about a year ago with the multcomp package.
Your sig.data can be plotted with the multcomp package with the following code. require(multcomp) tmp <- list(confint=sig.data) attr(tmp, "type") <- "none" old.oma <- par(oma=c(0,1,0,0)) multcomp:::plot.confint.glht(tmp) par(old.oma) You will get more control if you start with your aov object, rather than the derived sig.data object that you posted. ______________________________________________ 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.
