Hello, The ade4 package is now available on CRAN. ade4 is a multivariate data analysis package oriented towards statistical ecology. The main functions include one-table (PCA, COA, MCA, PCO, etc.), two-tables (PCAIV, Co-inertia, CCA, etc.) and k-tables multivariate analysis methods, with several Monte-Carlo tests and many graphical display methods. A complete documentation with many example data

Hello list, i have a glm with family=binomial, link=logit but there is over-dispersion. So, in order to take into account for this problem i choose to do a glm with family=quasibinomial(). I'm not an expert on this subject and i ask if someone could validate my approach (i'm not sure for the tests) : quasi_glm(myformula,quasibinomial(),start=mystart) summary(quasi) # test t for

Hello List, i need help for eigen and svd functions. I have a non-symmetric square matrix. These matrix is not positive (some eigenvalues are negative). I want to diagonalise these matrix. So, I use svd and eigen and i compare the results. eigen give me the "good" eigenvalues (positive and negative). I compare with another software and the results are the same. BUT, when i use svd,

Dear R user, I asked for packages which should be mentioned in a ecological related presentation of R and would like to summarize the replies. First of all E. Paradis pointed out, that he would prefer to see R presented in a different way, please read his whole reply https:// www.stat.math.ethz.ch/pipermail/r-help/2003-December/041951.html. Packages which

Dear R users, seqinR 1.0-5 has been released yesterday on CRAN, so that the source code of the package should be available on all CRAN mirrors within the next 24h.

Dear R-Users, ade4TkGUI is a new package available on CRAN. It implements a Tcl/Tk graphical user interface (GUI) for the ade4 package. Only the most basic functions of ade4 have a GUI in this first version : classical one-table data analysis methods (PCA, COA, MCA, PCO, etc.), one table with groups of rows (BGA, WGA, DA), and two-tables analysis methods (Coinertia analysis, CCA, PCAIV).

Dear UseRs, Version 0.2-1 of the ade4TkGUI package (a GUI for the ade4 package) is now available on CRAN. This version corrects a few bugs and has the following new features : - history management : commands executed in the GUI are now stored in the R session history - echo of commands on cosole : all commands (including these ones issued in the dudi synthesis window) are now echoed to the
