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.
