I want to plot quantitative data as a function of three two-level factors. How do I group the bars on a barplot by level through labeling and spacing? Here <http://www.thomaslevine.org/sample_multiple-factor_barplot.png>'s what I'm thinking of. Also, I'm pretty sure that I want a barplot, but there may be something better.

I would like to make bar plots where the bars are composed of text like this: http://www.thomaslevine.com/lowres/text_bars.png Is there a package that will help me with this? Thanks Tom

I am analysing occurrences of a phenomenon by time, and each of these timestamps taken from email headers represents one occurrence. (The last number is the time zone.) I can easily change the format.

...d kruskal.test. I compared the raising of an error among the three builds of R/kruskal.test. I ran these commands for each R version to build R, install the packages referencing kruskal.test, and run the tests in parallel. The procedure is available here; see the Makefile for more detail. https://thomaslevine.com/scm/r-patches/dir?ci=6ea0db4fde&name=kruskal.test-numeric/testing Run it with like this if you are so inclined. make -j 3 install make -j 3 test I found 100 packages that referenced kruskal.test. (This was based on a very crude string matching; some of these packages mentioned kruska...

I submit a couple options for addressing bug 16719: kruskal.test documentation for formula. https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=16719 disallow-character.diff changes the documentation and error message to indicate that factors are accepted. allow-character.diff changes the kruskal.test functions to convert character vectors to factors; documentation is updated accordingly. I

This isn't the typical r-help post, but I think people here will appreciate it. The current Shirt.Woot (http://shirt.woot.com) derby prompt is fake band names, so I chose the name "The Probable Error of a Mean." And I made my submission with R. Here it is: http://www.thomaslevine.org/the_probable_error_of_a_mean/poster.png http://shirt.woot.com/Derby/Entry.aspx?id=33029 I'm quite surprised and disappointed by how few people understand it. It's probably not going to win, but I'll print a few fake band propaganda materials and confuse/enlighten people. This is a...
