-------- Original Message -------- Subject: Re: CVA in MorphoJ vs LDA in R Date: Wed, 8 Sep 2010 15:18:14 -0400 From: Michelle Singleton <[email protected]> To: [email protected] Hi Stefan, I would very much like to test your R package. Many thanks, Michelle At 09:30 PM 7/15/2010 +0200, you wrote:
Dear Louis and Martha, the difference between lda in R and a cva - is that lda uses the covariance matrix and not the pooled within group covariance matrix. greetings Stefan BTW.: at the moment i am working on a Rpackage that implements sliding of surface and curve semilandmarks (on 3D-meshes including reprojection - using a very fast command line app coded on the base of vcglib (meshlab)), it also contains a cva and some tools for importing and exporting meshes that can be rendered by the rgl package and for importing data from and to "landmark" etc..... if someone is interested in testing (documentation is sadly abit behind), mail me.
