lattice plotting character woes
The following reproducable code shows the setting of my problem:
set.seed(260808)
n = 50
x = rnorm(n)
y = rnorm(n)
z = ceiling(runif(n,0,4))
g = runif(n,0,6)
G = factor(ceiling(g))
xyplot(y ~ x | G)
plsy <- trellis.par.get("plot.symbol")
plsy$pch = z
trellis.par.set("plot.symbol",plsy)
xyplot(y ~ x | G)
plsy$pch = as.character(z)
