Dear R users, I would like to draw some histograms as seen in the page whose address I wrote below. I searched through the web a lot and I found a page which describes how I can do it for older versions of R. For newer versions they recommend to install the package R.basics in R.clusters but this does not exist. The address of the web page is http://www1.maths.lth.se/help/R/plot.histogram/ Unfortunately I could not find any other resource or help. Is it possible to make histograms like I wanted with R? If so, could you please give any advise on how I can do it? Thank you, Regards, evrim [[alternative HTML version deleted]]
Dear Evrim, That is easy to do with the ggplot2 package. You only need the data in a "long" format. melt() is very usefull to convert data from a wide to a long format. library(ggplot2) n <- 100 Wide <- data.frame(X1 = rnorm(n, mean = -0.5), X2 = rnorm(n, mean = 0, sd = 2), X3 = rnorm(n, mean = 0.5)) Long <- melt(Wide) ggplot(Long, aes(x = value, fill = variable)) + geom_histogram(position = position_dodge()) #some alternatives ggplot(Long, aes(x = value, fill = variable)) + geom_histogram() ggplot(Long, aes(x = value)) + geom_histogram() + facet_wrap(~ variable) ggplot(Long, aes(x = value)) + geom_histogram() + facet_grid(variable ~ .)

Google for R.classes bundle which will get you to the appropriate page on the author's site where you can download and install it. Installing the bundle will install a number of packages including R.basic which contains plot.histogram.

Personally I find those types of plots difficult to interpret. Much easier to create, view, and interpret is to simply plot the lines from density estimates. See the density function or the logspline package. -- Gregory (Greg) L.

Or use frequency polygons, if you want to stay with the interpretability of a histogram.

Check out: ggplot2 (http://had.co.nz/ggplot2/) This R library is also good at developing histograms. Good luck. --- On Wed, 3/25/09, evrim akar <evrim.akar at gmail.com> wrote:> From: evrim akar <evrim.akar at gmail.com> > Subject: [R] histogram plots with many different samples > To: r-help at r-project.org > Date: Wednesday, March 25, 2009, 9:40 AM > Dear R users, > > I would like to draw some histograms as seen in the page > whose address I > wrote below.
