## ladderize object
anoletree_ladderized<-ladderize.simmap(anoletree)

## plot unladderized & ladderized
par(mfrow=c(2,1))
plot(anoletree,ftype="off",direction="upwards",
    mar=c(1.1,2.1,2.1,1.1))
mtext("a) unladderized tree",adj=0)
plot(anoletree_ladderized,ftype="off",
    direction="upwards",mar=c(1.1,2.1,2.1,1.1))
mtext("b) ladderized tree",adj=0)

## reset par to default
