On request from Martin Maechler I suggest the following improvement to base::plot.histogram(), which makes it possible to plot several histograms next to each other in the same plot by making them sharing space. You can set the width and the offset the bars should have. Example:
x1 <- rnorm(1000, 0.4, 0.8) x2 <- rnorm(1000, 0.0, 1.0) x3 <- rnorm(1000, -1.0, 1.0) hist(x1, width=0.33, offset=0.00, col="blue", xlim=c(-4,4), main="Histogram of x1, x2 & x3", xlab="x1 - blue, x2 - red, x3 - green") hist(x2, width=0.33, offset=0.33, col="red", add=TRUE) hist(x3, width=0.33, offset=0.66, col="green", add=TRUE) More info and code can be found (for a couple of weeks) at http://www.maths.lth.se/help/R/plot.histogram/ Best wishes Henrik Bengtsson ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-devel
