R help - Apr 2014 - how to change annotations in contour function from rsm package

Dear All,

I am using R3.0.3 and rsm 2.04. Since I want do log transformation on my
data, so I want change annotation of "Slice at ..".  For example, I
want
change (Slice at W = 1.25, L=2) in the first graph into (Slice at W log(1.25),
L=log(2)). Can anyone tell me how can I change it?

Thanks

library(rsm)
heli.rsm <- rsm(ave ~ block + SO(x1, x2, x3, x4), data = heli)
windows(width=10.8/2*3, height=10.8)
par(mfrow = c(2, 3))
contour(heli.rsm, ~ x1 + x2 + x3 + x4, image = TRUE)
