...9;ve found so far is the section in "An Introduction to R" (http://cran.r-project.org/doc/manuals/R-intro.html#Formulae-for-statistical-models). Does anyone have any other suggestions? I have a few questions about the definitions given in "An Introduction to R": * "M_1 : M_2 - The tensor product of M_1 and M_2. If both terms are factors, then the ?subclasses? factor." From my reading, the usual interpretation of a tensor product when x and y are vectors is the outer product. I don't see how that would work here - how does a matrix work as an predictor in...

Dear R users,   I need to do a F test on the hypothesis that a 2 by 1 vector (X_1, X_2)' has the mean vector  (M_1, M_2)'. Specifically, I would like to assume the X vector comes from a bivariate Normal distribution (M, Sigma). Then, given 1000 observations on X, I wanted to test if the means of X agree with the means of the target Normal distribution. Any function or package in R could do such a test? Thanks!  ...

Hi all, Is there an easy way to do cumulative matrix multipliation in R? What's the syntex? Thanks.

Hello, i use i.e. the cluster-package and the fanny-object to construct some cluster's and get the membership'S for every "Person" & Cluster ! My finally problem is to match efficient the data and the results's togehter in one table! Until now i use the ODBC-Package and save both in a access-file and copy them together, but i can't be sure that the sorting is the
