I've now processed this document through Acrobat software. The navigation keys in Acrobat Reader should now handle it properly. The other advantage is a dramatic reduction in size, to half a megabyte. The new file is http://wwwmaths.anu.edu.au/~johnm/r/r4dat-gr.pdf Data sets [use source() to access them from an R session] are in the same directory, i. e. http://wwwmaths.anu.edu.au/~johnm/r/ The scripts are in the file: http://wwwmaths.anu.edu.au/~johnm/r/r4dat-gr.dis One of the fonts is a bit fuzzy in the screen display....

I have posted, at http://wwwmaths.anu.edu.au/~john/r/newsets/ image (.rda) files, and first stabs at .Rd files for various data on deaths in London from 1629 to 1939. (There are of course gaps.) The sources (Guy 1882 & Stocks 1942) are documented in the .Rd files: (1) poxetc: measles, smallpox & total deaths: 1629-1881 [I...

...g outside the plot area, where they can overlap other graphical features. The parameter label.pos allows users to change this default. The modified code that I propose is below. This, a modified .Rd file, and files from diff used with the April 20 development version, are in my directory http://wwwmaths.anu.edu.au/~johnm/r/plot-lm/ I believe the Residual-Leverage plot is given in Krause & Olsen, whether with Cook's distance contours I do not recall. I do not have access to a copy of this book. Martin Maechler drew my attention to it in 2003, as superior to the Cook's distance plot....

I'm looking for a Windows distribution of TeX that works with R, after a few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is still recommended, but it turns out that fptex is "defunct" as of May 2005, see http://www.metz.supelec.fr/~popineau/xemtex-7.html So, what is suggested? TUG (tug.org) recommends something called proTeXt, which is said to be

I have just put up a new version of this 109 page pdf document, at: http://wwwmaths.anu.edu.au/~johnm/r-notes/r-notes.pdf The file containing the scripts (r-intro.dis) is in the same directory, as are datasets [.R files; use source(<filename>)] that are not in the current R libraries. This replaces a version that had been posted earlier this week, in which the final charac...

There are now separate scripts for each chapter, except that 1&2 have been combined and 3&4 are combined. I changed the name because John Braun and m...

Dear all, is there an easy way to create error bars for the following types of plots: a) barplots b) interaction plots Many other statistics packages (e.g. Statistica) offer very nice interaction plots with error bars, and I??d like to be able to do the same in R. Best regards Christoph

Hi there, I downloaded version 1.9.1 WinZip file, 9.367 bytes ( so I can update my R and use the vcd package) but cannot get the download from your Web site to unzip and install. So silly! The error message is :" Error reading header after processing 0 entries." I tried downloading from 3 different URLs, all yielding the same message when I try to unzip and install the file.

Hi, how can I do multinomial logistic regression in R? I think glm() can only handle binary response variable, and polr() can only handle ordinal response variable. how to do logistic regression with multinomial response variable? Thanks __________________________________

I was hoping someone could help me! How do you exclude outliers from a set of data? Thanks, Laura [[alternative HTML version deleted]]

I write to ask you an help about the package gregmisc. I saw the instructions, and I need some functionalities of this package, but I am unable ti download it. On friday I was able to download thte .zip, but R does not install this package, today there is no possibility to download it. What I have to do? Thanks Anna Maria Paganoni Anna

hi all i am busy teaching a regression analysis course to second year science students. the course is fairly theoretical with all of the standard theorems and proofs... i would like to give the class a practical assignment as well. could you suggest a good problem and the location of the data set/s? it would be good if the data set has been analysed by a number of other people so that students

Hi to all, I am a PH.D Student doing statistical analysis. I am totally new to R. I previously use Stata and am changing into R. I ususally do with logit regression with binary dependent variable (war occurence:1 or 0). I just want to know command to do that. More sepcifically, Let say, my Y is war occurence (occur=1, otherwise 0). And my independent variables (Xs) are trade, democracy,
