Hi everyone, I have the following problem: I want to perform a LDA with the function lda(). My data object mat.data is a matrix with dimensions
> dim(mat.data) [1] 1228 44 and my grouping vector grp has length 1228: > length(grp) [1] 1228 Every time I call lda(), the following error message occurs: > lda(mat.data,grp) Error in lda.default(x, grouping, ...) : length of dimnames [2] not equal to array extent In order to find the error I created a matrix mat.test mat.test<-matrix(1:500,nrow=1228,ncol=44) with arbitrary entries an the same attributes as mat.data: > dimnames(mat.test) NULL > dimnames(mat.data) NULL But with the test object mat.test there occurs no error ! Can somebody help me, this really makes me crazy, thanks, Robin ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
