[R] Controlling Order of Panels in Lattice Trellis Plots

[Bert Gunter]

You do not need to use ordered factors.

newfac <- factor(oldfac, lev= ...) ## will do it. e.g.

> x <- factor(letters[1:3]) ## default ordering is alphabetic (mod locale)
> x
[1] a b c
Levels: a b c
> y <- factor(x,lev=letters[3:1])  ## reorder the levels
> y
[1] a b c
Levels: c b a
