Simple question (I hope?). How does one extract the data from a trellis
object? I need to get the data from a call to histogram().
A simple example below...
dat<-data.frame(year=as.factor(round(runif(500, 1990, 2010))), x=rnorm(500,
75, 35),
y=rep(seq(1,50,by=1), times=10))
histogram(data=dat, y~x | year, type='count')
How do I get the actual numbers plotted in the histograms from this call to
histogram()?
Thanks,
Tim
