It's hard to design a graph like this that looks good, but it's easy to draw using add=TRUE: x <- rnorm(1000) y <- rnorm(1000, mean=1) breaks <- pretty(range(c(x,y)), 20) hist(x, breaks=breaks, col='red', main="Hist of x and y") hist(y, breaks=breaks, add=TRUE, border='blue') Duncan Murdoch ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
