Hi all:
I am trying to do PCA on the following matrix.
N1 N2 A1 A2 B1 B2
gene_a 90 110 190 210 290 310
gene_b 190 210 390 410 590 610
gene_c 90 110 110 90 120 80
gene_d 200 100 400 90 600 200
>dataf<-read.table("matrix")
> pca<-princomp(dataf,cor=TRUE,scores=TRUE)
Error in princomp.default(dataf, cor = TRUE, scores =
TRUE) :
princomp can only be used with more units than
variables
Can any one help me, whats wrong here.
thanks
srini
