Hey, Rajesh
I bit light on detail here. Being a mind reader is not an R-help
prerequisite. However since I have been working on histograms today and
you've just posted a question using ggplot, let me guess that its ggplot you
are refering to. Then here is an example, which you can find in my post a
few posts previous to yours. I've added scale_ commands to restrict the x
and y scales. Actually in this example both histograms get plotted on the
same y-scale automatically so that command can be removed.
Check out the ggplot on line reference http://had.co.nz/ggplot2/ and book
http://cran.r-project.org/web/packages/ggplot2/ggplot2.pdf
hth
require(ggplot2)
x <- data.frame(value=rnorm(5000, mean=0), case="A")
y <- data.frame(value=rnorm(5000, mean=3), case="B")
xy <- rbind(x, y)
ggplot(xy, aes(x=value, fill=case, group=case)) + geom_histogram(alpha=0.5,
binwidth=0.1, position="identity") +
scale_x_continuous(limits=c(-2,3)) +
scale_y_continuous(limits=c(0,250))
