Not really but a better plot call would be
plot(x.hist,col=ifelse(x.hist$breaks<0,"red","green")) Ross Darnell -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alberto Monteiro Sent: Tuesday, 18 September 2007 6:12 AM To: [EMAIL PROTECTED] Subject: [R] Histogram with colors Is there a simple way to plot a histogram with colors? For example, suppose I generate random points in the N(2,1) distribution: x <- rnorm(100000, mean = 2, sd = 1) Now I would like to plot the histogram: hist(x) but I would like to show the bars with x < 0 in red, and the bars with x >= 0 in lightgreen. Is there any simple way to do it? I think I can do it in two steps: x.hist <- hist(x, plot=FALSE) plot(x.hist, col=c(rep("red", 5), rep("green", 12))) but maybe a more direct way is available.
