My question is based on an example provided in the following: Referencing: Statistics with R Vincent Zoonekynd <zoonek at math.jussieu.fr> 6th January 2007 URL: http://zoonek2.free.fr/UNIX/48_R/all.html data(HairEyeColor) a <- as.table( apply(HairEyeColor, c(1,2), sum) ) # Provided Example barplot(a, beside = TRUE, legend.text = attr(a, "dimnames")$Hair) # I would like...

...Would also if could also do something like what "qplot" allows, i.e. doing stacked histograms.  I would like the "staked" histogram values to show age.   Thanks for any feedback and insight that can be provided.   * Amongst many others, thanks to : (1) Statistics with R, Vincent Zoonekynd, <zoonek@math.jussieu.fr> (2) An Introduction to R: Software for StatisticalModelling & Computing [[alternative HTML version deleted]]

Hi, I've been looking for Image Processing packages. Thresholding, Edge Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab etc. would be a good address but then I'm missing the "statistical power" of R. Does anybody know of packages, projects etc. Comments on wether the use of R for such matters is useful are welcome. Greetings Thomas Kaliwe

...ibution so they do line up perfectly in the second qqnorm(). Is that what's happening?

* What were your biggest misconceptions or stumbling blocks to getting up and running with R? * What documents helped you the most in this initial phase? I especially want to hear from people who are lazy and impatient. Feel free to write to me off-list. Definitely write off-list if you are just confirming what has been said on-list. -- Patrick Burns pburns at pburns.seanet.com
