Is this what you want? dataset <- data.frame(x = c(rnorm(100), runif(100), rchisq(100, 1)), y = gl(3, 100, labels = LETTERS[1:3])) ggplot(dataset, aes(x = x, fill = y)) + geom_histogram() ggplot(dataset, aes(x = x, fill = y)) + geom_histogram(position = "dodge")

Borchers Verzonden: dinsdag 8 juli 2008 13:23 Aan: r-help@r-project.org Onderwerp: [R] Histogram with colors according to factor Given a data frame with a continuous variable and a factor. I would like to generate a histogram of the continuous variable, where each bar is filled with different colors according to the percentage of factor values falling into this region of the continuous variable. I looked into packages like 'lattice' and 'ggplot2'. Searching R-help revealed that 'histogram' is spelled 'histogramm' in almost 2% of the time. I now know how to color whole bars, but did not find a solution for this specific kind of visualization. Many thanks in advance, Hans Werner Borchers ---- Hans W.
