xyplot (lattice): colours of lines
using either one of the following codes:
xyplot(X ~ time | center, type="l", panel=panel.superpose, groups=subject,
col = treatment)
xyplot(X ~ time | center, groups = subject,
panel = function(x, y, ...){
panel.superpose(x, y, col = treatment, type = "l", ...)
})
I get two different colours for the lines by these colours do not match the
corresponding
treatment
