Hi Everybody:

I want to draw some chart using command "histogram" and add another curve in it.

histogram( ~ height | voice.part, data = singer, nint = 17,  endpoints = c(59.5, 76.5), layout = c(2,4), aspect = .5,  xlab = "Height (inches)")

Now I got a chart of 8 blocks, then I need add :" abline(v=mean(singer$height), col=2, lwd=2) " or any other curve to every block.
How can I do to achieve it. Thanks.

Best Regards
