Suppose I do a psychology experiment in which each of six subjects does several items in each of five fixed conditions, A, B, C, D, and E. The items are randomized separately for each subject, so I can ignore order. All I want to know is whether the five conditions differ. The data look like this. Each row is a subject, and each number is the score in the given condition. A B C D E 4 1

For those new to this list, I point out that Yuelin Li and I have drafted an introduction to R for psychology, trying to emphasize the things the psychologists usually do. It is at http://www.psych.upenn.edu/~baron/rpsych.pdf and http://www.psych.upenn.edu/~baron/rpsych.htm Because it is a draft, with frequent changes, we have not yet asked for it to be placed in the CRAN page. We welcome

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

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,

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,

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

The 11th seems to be needed.

I am analyzing data from an experiment with two factors: Carbon (+/-) and O3 (+/-), with 4 replicates of each treatment, and 4 harvests over a year. The treatments are assigned in a block design to individual Rings. I have approaches this as a repeated measures design. Fixed factors are Carbon, O3 and Harvest, with Ring assigned as a random variable. I have performed repeated measures analysis

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

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

Unfortunately, I am unable to get this search site working again. (The message below explains why I had to rebuild it.) The computer worked for the better part of a day downloading and installing all the help files from all CRAN packages. Somehow it failed to get the vignettes this time. But I pushed ahead and ran the part of namazu that makes the search indices: mknmz. And you can see the

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 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

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. The direct link to the

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

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:

I would like to impute missing data in a set of correlated variables (columns of a matrix). It looks like transcan() from Hmisc is roughly what I want. It says, "transcan automatically transforms continuous and categorical variables to have maximum correlation with the best linear combination of the other variables." And, "By default, transcan imputes NAs with "best

In Baron and Li's "Notes on the use of R for psychology experiments and questionnaires" http://cran.r-project.org/doc/contrib/rpsych.htm they describe a balanced data set for a drug experiment: "... a test of drug treatment effect by one between-subject factor: group (two groups of 8 subjects each) and two within-subject factors: drug (2 levels) and dose (3 levels).
