lattice: adding information on number of observations
Dear R-users,
I am using R version 2.9.1 and lattice 0.17-26 under windows.
In a lattice boxplot, I would like to add information on how many observations each singel boxplot is based upon.
For example (the basic plot):
# Begin R-code
library(lattice)
dat <- data.frame(panvar = rep(c("A","B","A","B"), c(3,7,4,6)), grp = rep(c("grp1", "grp2"), c(10,10)), val = rnorm(20))
dat
bwplot(val ~ grp | panvar, data = dat)
# End R-code
As in my real life data the number of observations in each subgroup will be quite diff...
