I can't figure out how to customize the order of the panels for effects plots. Any help would be appreciated. Here's my code: library(effects) lm.hour3eff<-allEffects(lm.hour3, xlevels=list(road=c(0, 1000, 2000, 3000), trail=c(0, 1000, 2000, 3000))) plot(lm.hour3eff,"road:trail", xlab="Trail Distance (m)", ylab="Step Length (m)", main=NULL) Thanks, McCrea -- View this message in context: http://www.nabble.com/order-of-effects-plot-panels-tp25123680p25123680.html Sent from the R help mailing list archive at Nabble.com.
