[sorry if this arrives in duplo: it doesn't show up in the archives and it seems that the address I posted this from originally is no longer functional] Hello, I think I could do with some suggestions concerning the following problem. I have data from a set of experiments on motion sickness where for each subject, I have 1) personal data like age and gender 2) a subjective rating of

Hello, I have some data in a data.frame where for each of a number of subjects, I have scores for all of a number of symptoms. Subjects are subdivided in a number of groups, which have unequal sizes. I'd like to plot between-group differences in the scores on the various symptoms. Ideally, that would be in a form as would be produced by > bwplot( Score~Symptom ) but I'm not sure

This may be of interest: http://www.ijs.si/software/snprintf/ It looks like this version may well be more complete and conform the standards than the version that comes with R. BTW: I am currently patching unix/sys_std.c and modules/gtkconsole.c such that they don't store lines in the history that are identical to the previous line. Is there any interest in posting those patches here? RenE

It doesn't print anything: the summary.aov (or summary.aovlist) print method does. ?summary.aov tells you the structure of the objects they return. On Tue, 15 Feb 2005, RenE J.V.

Dear All, There is no advantage of GUI over CLI, IMO. The real issue is the answer to the questions: "What should I do next?" or "What am I allowed to do here?" A "nice" interface, not necessarily GUI, will offer friendly answers: "I was expecting you to do _this_" or "In this situation you are allowed to do _these things_" You see, it's all

Is there an equivalent to traceback() for tracing a warning message? Since upgrading to 1.6.0, I get a message, at startup, that "the use of _ is deprecated". I've never used this operator in any of the functions I wrote, so some library must use it. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

There is an incompatibility between R's configure/build process, and gcc 3.2.0 (and maybe earlier). Gcc 3.2.0 includes -I/usr/local/include by default, on my system (default configuration), and cpp0 issues a warning when this flag is issued additionally by the user (= R's configure). This warning ends up in the dependency sections of the Makefile that are generated

I am simulating sickness among a group of families. Part of the task is to randomly draw who in the family will be sick, randomly drawing from family ID's where Dad =1, Mom = 2, Kid1 = 3, Kid2 = 4., etc. My census of Dads is of the form shown below.

Hello, This is a usage question for others with experience of R under the Aqua Mac OS X interface. Basically, I don't succeed in importing PDF files (created with the 'Save As' menu to Quartz device windows) into Illustrator. Versions up to (and including?) 10 loose paths (lines/polygons) and or fill them in black. Version CS (11) on the Mac imports almost correctly, but, "to

Starting html help in the current version of R has a very annoying side-effect. It indiscriminantly removes $HOME/.R, and replaces it with a virgin copy. I discovered that when all of a sudden I got complaints about my startup "library" not being found. Below is a modified version of the script that doesn't do this. It is not perfect yet (it shouldn't try to recreate links
