Question

I am creating a barplot in R and want to color each bar by bar height (count)

Currently what I have:

z=rnorm(n,1)
Z=runif(n)
h=barplot(Z)

I have pictures but not enough reputation to post them.
So here is the example in MatLab:

Answer 1

Try this,

library(ggplot2)
d = data.frame(x = rnorm(100))
ggplot(d) + geom_bar(aes(x, fill = ..count..))
