Hello, All: Jonathan Baron is "giving up" maintaining the RSiteSearch database. This breaks three things: (1) The R Site Search web service that Baron has maintained. (2) The RSiteSearch function in the utils package. (3) The sos package, for which I'm the maintainer and lead author. Might someone else be willing to take these over? For me,

Don't do anything yet. I may have found the problem by accident. I tried to use the computer from something else, and it was being drastically slowed down by some leftover processes, which turned out to be xlhtml. That is something that converts Excel files. Apparently, some excel files got into the libraries, and they were causing the indexing to hang completely. I am now running everything

Does anyone know how to read a SYSTAT .syd file on Linux? (Splus 6 does it, but it is easier to find a Windows box with Systat than to download their demo. I'm wondering if there is a better way than either of these options.)

Hi, is there an graphics overview, where the graphic capabitlities of R are shown with the corresponding code? I already tested 'demo(graphics)', that isn't that comprehensive, 'demo(image)', 'demo(lattice)', searched the Mailarchive, googled and the FAQ keeps silent, too. For example, I know how a special graphic I need should look like, but I don't know

My search site, http://finzi.psych.upenn.edu, has had several problems recently, all my fault, for which I apologize. But it now seems to be running reliably, on a new computer that is much faster than the old one. It uses htdig to permit search of the Rhelp mailing list, R documents, R functions, and various combinations of these. Search has several options, including Boolean search (with AND,

Is there a way to get a reference list of journal articles that have used R? I am just looking for some examples of R graphs and presentation of results where R was used to generate the results. Thanks for any feedback and insights.

Hello, I am analysing several samples whose sizes are from 9 to 110. I would like to test their distribution with R, whether they are normal or not. I wonder which test for normality from R should I use . Thank you for help.

I believe eigen(), svd() and qr() can all do it.

The 11th seems to be needed.

For my R page at http://finzi.psych.upenn.edu/ (also the target of RSiteSearch()), I'm trying to find a way to get the html versions of the help pages without actually installing packages. This will allow me to include packages that don't install. And it will also vastly speed up the monthly update, and make it easier to replicate everything in case of disaster. I have made a modified

I cannot discover how to set or find the working directory in Rweb, so that I can source() a file from the server. The file I source() must refer to a data file in its directory. setwd() does not do anything, and getwd() says that the working directory is in /var/www/cgi-bin/ (on Linux). (I have a student who installed R on her own computer and analyzed half of her data, and then her computer

The documentation says, "pmax and pmin take several vectors as arguments and return a single vector giving the parallel maxima (or minima) of the vectors." I discovered that, if you use a matrix or array instead of a vector, pmax returns a matrix or array, respectively. This makes pmax and pmin much more useful, and should not be left to people to discover on their own! For example:

hi, I have a matrix (representing original data) that looks e.g. like this (consider it beeing x,y,z coords): 441 447 0 265 407 0 374 223 0 288 574 0 669 309 0 591 195 0 595 475 0 424 351 0 I get a second matrix (subject data) that is similiar to the above matrix but it is scaled, translated and rotated (and of course a little inprecise). Also I have an

By way of review, most large Web sites allow the user to create *bookmarks* which link to pages inside the Web site. However, here, the pages have one of just two URL's: http://www.r-project.org and http://cran.r-project.org The reason is the way HTML *frames* are used in setup of the Web site. It would be very helpful if the Web site were revised so that many if not most pages had

Dear Colleagues, Occasionally I deal with computer-generated (i.e., websurvey) data files that haven't quite worked correctly. When I try to read the data into R, I get something like this: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 26 did not have 648 elements ...is there any way to get R to tell me how many elements line 26 *did* have? That

I have always avoided missing data by keeping my distance from the real world. But I have a student who is doing a study of real patients. We're trying to test regression models using multiple imputation. We did the following (roughly): f <- aregImpute(~ [list of 32 variables, separated by + signs], n.impute=20, defaultLinear=T, data=t1) # I read that 20 is better than the default of

I want to write a function to take an argument as the response variable of a linear model, e.g. to do anova's across a list of variables, something like the following (except, of course, this doesn't work): function(x) { anova(lm(x ~ my.factor,data=my.data)) } The x in lm() above is getting evaluated at the wrong level. How can I make this work? -- Russell Senior ``The two

Dear all, I could not draw a forest plot for meta-analysis under ramdon models using the rmeta package. The rmeta has a default function for MH (fixed-effect) model. Has the rmeta package been updated for such a function? Or someone revised it and kept a private code? I would appreciate it if you could provide some information on this question. Thanks, Andrew This email is intended

It used to be that, whenever I added or updated a new package, the file /usr/lib/R/doc/html/packages.html would be updated (on Linux). Now I find that this does not happen anymore. So I found this function make.packages.html, which seems to do what I think should be done automatically. But it puts its output in a file in /tmp/..., which I then have to move, in an extra step, to where it should

The Goodman/Kruskal gamma is a nice descriptive rank-order correlation statistic, often used in psychology. It is nice because it is easy to understand. It takes all pairs of values of each variable and asks whether they are congruent (S+ is the number in the same order for both variables) or discordant (S-, opposite ranking). The statistic is (S+ - S-)/(S+ + S-). It is like tau except for the
