For #1 it would be easier to just use 2 columns so that there is no question of alignment in the first place, i.e. ncol = 2. For #2 try drawing the legend from lower level functions such as text since text does respect lheight. See the source of legendg in plotrix for how to do that. -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ 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.
