Hi all, I wondered how I can get the translated, rotated and scaledmatrix in a procrustes analysis. This does not help:
############################## library (vegan) #defining the target matrix: a= cbind (c (1,2,3,4), c( 10,12,14,16)) #defining the matrix to be rotated: b= a; b[,2]= c(9,11,15,16) c=procrustes (a,b); g=fitted (c) # trying to get to the procrustes matrices: d= t (apply(b,1,'-',c$translation)) #points ( d, col=4) e= d %*% c$rotation #points ( e, col=6) f= e* c$scale #points ( f, col=7) # Should be a matrix(0,3,2) but is not: f-g #(!) Thanks in Advance. -- View this message in context: http://r.789695.n4.nabble.com/Obtaining-translated-rotated-and-scaled-matrics-in-procrustes-analysis-tp4589030p4589030.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
