Dear list, has anyone written a package/function in R for computing a point- biserial resp. biserial correlation? Thanks in advance Bernd

...ble. I would have expected something like: gsub("\\","\/","c:\My Documents\data.dat") to work but it does not (incorrect regular expression). Note that I have no control on the string which is returned from the system (no such problem under Linux BTW). Any idea ? Yvonnick NOEL U. of Rennes 2 FRANCE

Hi I am having problems with the rendering of scientific symbols (mu and degree) in my plots. Whenever I use these symbols they are rendered changed (mu is changed to the proportionality symbol and degree is changed to something resembling a gamma) in the X-device. If I make a pdf of the plot and open the file in Evince or Okular symbols are also rendered wrong, however if I open the file

...st standard statistical tests may well be presented as a simple comparison between GLMs and this is the way I go with my students here. This allows an integrated presentation for almost all common (and simple) situations in social sciences. More information is available on my webpage : http://yvonnick.noel.free.fr/r2stats [in French for the moment, although the package is in English]. Installing the package is done from a temporary repository: install.packages("R2STATS",repos="http://yvonnick.noel.free.fr/cran",dep=TRUE) if you already have a recent version of GTK+ and RG...

I cannot find what is the function label for matrix inversion in R. I have found 'ginv' for the moore-penrose in the MASS package, but there is probably a simple inversion operator in the base package. Where can I find it? ____________________________________________ Yvonnick Noel, PhD.

Dear friends, My R*C table is as follow: better good bad Goup1 16 71 37 Group2 0 4 61 Group3 1 6 57 Can I test if there are statistical significant between Group1 and Group2, Group2 and Group3, Group1 and Group2, taking into the multiple comparisons? The table can be set up using the following program: a<-matrix(data=c(16,71,37,0,4,61,1,6,57),nrow=3,byrow=TRUE) Thanks

...provided. The problem is: This approach creates a whole matrix of subsets of r integers among 1:n, which rapidly gives huge matrices, and this is clearly not optimal for the real data provided above. Would anyone have a suggestion as to an alternative and more efficient strategy? Good luck, Yvonnick Noel University of Brittany, Rennes 2 France

...also added a "PATH=...\rw1010\" line in my autoexec.bat, but this does not seem to have any effect. As I am no expert at Lisp (nor at EMACS), could somebody be so kind as to tell me what are the (probably very simple) manipulations to do to have all this work?

Hello all, To anyone who is interested, I'm trying to learn a bit more about developing applications in R with user interfaces. I've been playing around with gWidgets to develop a model building interface. I'd appreciate any comments, suggestions, or guidance on how to better structure my R code and organize the programming task. In addition, any suggestions for features and
