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.)

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,

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

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

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.

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

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:

Hello r-supporters! I?m working with contributed packages downloaded today.When I try to install them with R CMD INSTALL an error message says that the package is not a gzip file. This occurs both in Suse 7.3 and in Debian Potato 2.2. I had not this problem when instaled the same packages just half a year ago. I think this is related with cuestions about GNU license or similar but, knows

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

Hello everyone, I am new to this list and the R-Project, so I hope my question is not trivial or has been answered before. I searched the FAQs and the mailing list archives and I could not find anything about Conjoint Analysis. I am especially interested in Choice-based Conjoint, resp. discrete choice models. Is there a function / module that handles this issue? Or can the multinomial logit

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

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

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

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.

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

First, my site will be down December 27-28 because of a network upgrade at Penn. It will also be down at least one day before that, while I upgrade the operating system. (And another day some time in January because of a planned power outage.) Second, I have replaced the search engine in my R site: http://finzi.psych.upenn.edu/ I am now using Namazu instead of HtDig.
