Hi,
I've been passing the hist() function to tapply() to quickly generate histograms based
on the list of factors supplied to tapply(). However, I have not figured out how to
generate titles for each of the histograms, which paste in the unique values of the
list factors as part of the histogram title. I'm hoping that someone can tell me how
to do this.
Thanks for your time and consideration,

I can't see it with talpply, but mapply and split works:
test <- rnorm(1000)
fac <- factor( rep(1:5, 200))
par(mfrow=c(2,3))
mapply(hist, split(test, fac), main=levels(fac))
