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.

This message is aimed at anyone who may be using exercises from my book with John Braun for teaching purposes. I am using this channel of communication in the absence of any other obvious effective channel. I ask the forbearance of list members. Our intention is to post solutions to selected exercises (the more challenging exercises) on the web, via a link from

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 character (mostly an

I am failing to get compactPDF to make any change to a pdf file that, a/c to the message from the CRAN upload site, can be very substantially compacted. Any ideas what may be wrong? I have also tried recreating the pdf file. I also tried R CMD build --resave-data --compact-vignettes DAAG The data files compact alright (but I get the 'significantly better compression' warning message

I propose the following enhancements and changes to plot.lm(), the most important of which is the addition of a Residuals vs Leverage plot. (1) A residual versus leverage plot has been added, available by specifying which = 5, and not included as one of the default plots. Contours of Cook's distance are included, by default at values of 0.5 and 1.0. The labeled points, if any, are those

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 have deliberately left several inconsistencies that were in

I find that if start R-2.6.0 in a workspace with no .RData file, load one of my workspaces from R-2.5.1 or earlier into R-2.6.0, and then before doing anything else type postscript(file="z.ps"), I get:: > ls() character(0) > load(url("http://www.maths.anu.edu.au/~johnm/r/test5.RData")) > postscript(file="z.ps") Error in postscript(file = "z.ps")

Although the specific behaviour that was reported has been fixed, bugs remain in Sweave's processing of comment lines when keep.source=TRUE This is in some senses a follow-up from earlier bugs. Hence the query -- what is the preferred procedure, to submit a new bug report? (Another option might be to add a comment to the web page for bug 14459.) Is there now a preference to submit via

The inst/doc directory of the DAAG package has 6 files coral551.spot, ... that are around 0.85 MB each. It would be useful to be able to zip then, but that as matters stand interferes with the use of the Sweave file that uses them to demonstrate input of expression array data that is in the "spot" format. They do not automatically get unzipped when required. I have checked that

./configure works fine. make generates the error ...... gcc -g -O2 -I../include -I../../src/include -c saveload.c -o saveload.o In file included from /usr/include/sys/turnstile.h:12, from /usr/include/sys/t_lock.h:20, from /usr/include/sys/vnode.h:37, from /usr/include/sys/stream.h:21, from /usr/include/netinet/in.h:38,

I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1. I start R by clicking on the R-2.31.0 icon. I'd assumed that it was a change that came with R-2.13.0! (On 32-bit Windows XP, which I have just checked, I do indeed get the 8.3 paths.) > R.home() [1] "C:/Programs/R/R-2.13.0" > sessionInfo() R version 2.13.0 (2011-04-13) Platform:

Can anyone suggest an equivalent, for lattice graphs, of the base graphics argument bty="l"? NB that I am leaving off the box around the strip, with a strip function: stripfun <- function(which.given,which.panel, factor.levels=as.expression(levlist), ...){ panel.text(x=0, y=0.5, lab = as.expression(levlist[which.panel[which.given]]),

Here is an example, modified from the help page to use test="Cp": -------------------------------------------------------------------------------- > fit0 <- lm(sr ~ 1, data = LifeCycleSavings) > fit1 <- update(fit0, . ~ . + pop15) > fit2 <- update(fit1, . ~ . + pop75) > anova(fit0, fit1, fit2, test="Cp") Error in `[.data.frame`(table, , "Resid.

I have placed my ~100 page document: Data Analysis and Graphics Using R - An Introduction at http://www.maths.anu.edu.au/~johnm/r-notes/r-notes.pdf The best way to access and print it is with Adobe Acroread Reader. I am making it available "for personal study and classroom use". It is a pdf version of a Word 95 file. A code that prints as ??, and which I have been unable to

I came across this notice of an upcoming webinar. The issues identified in the first paragraph below seem to me exactly those that the R project is designed to address. The claim that "most research software is barely fit for purpose compared to equivalent systems in the commercial world" seems to me not quite accurate! Comments!
