-------- Original Message -------- Subject: 3D CVA deformation in R Date: Thu, 17 Sep 2009 17:04:02 -0700 (PDT) From: Andy Grass <[email protected]> To: [email protected] Hi everyone, this may be a loaded question, but I'm trying to get a graphical representation of CVA deformation in R, and I keep hitting road blocks. I already have the relative warps calculated from SAS (saved as a .csv file) and I can get R to do the linear discriminant analysis on them just fine but I can't for the life of me figure out how to get the wireframes deformation like on page 255 of Morphometrics with R. The roadblock comes when I get to msh<-apply(m, 2, mean), which then wants me to define m, which needs me to define AP, which needs me to define orp (which wants centsiz and mshape), pgpa and aligne and so on and so forth, and it all seems to to be going back to functions to deal with the original procrustes. I think the problem is I just don't have the data in the correct array form, maybe? Does anyone have any advice? Or know of any other ways to get a graphical representation of 3D CVA deformation?
