[R] separate y-limits in xYplot panels

Hello,

I would like to get the scales of y-axes dependent only on the data points in a particular panel. Have attached a test example below. When using 'relation="free"', it does not make the scales 'free', however when using 'relation="sliced"', I get a warning "Explicitly specified limits ignored in: limitsFromLimitlist(have.lim = have.ylim, lim = ylim, relation = y.relation," (although in this particular case, I get the desired result, but in my real data, I do not get the free y-scale for each panel). Can you please let me know what should be correct syntax?

Thanks.

library(Hmisc)

test1 <- data.frame(

                    y = c(rnorm(33), rnorm(33, mean=10),
                    rnorm(34, mean=100)),
                    x = 1:100,
                    f = factor(c(rep("a", 33), rep("b", 33), rep("c", 34))),
                    g = factor(sample(LETTERS[1:2], size=100, replace=TRUE))
                    )


CI <- rnorm(100)

lb <- test1$y - CI
ub <- test1$y + CI

xYplot(Cbind(y, lb,ub )~x|f,

       groups=g,
       scales = list(relation="free"), ## Changing it to sliced gives warning
       data=test1)
