Very simple question: I would like to know the max bin height in a histogram. My call is

ggp <- ggplot(data = xq, aes(xp)) + geom_histogram(binwidth = 0.02,

boundary = 0)

where xq is a data frame containing xp. This makes a nice histogram, but I haven't been able to discover how to find the max bin height without reproducing the entire histogram myself, which is obviously possible but undesirable.

I am working on an iMac using RStudio.

Thanks in advance,
