i am trying to use multest R package(source package) and i am puzzled by the following: 1-What kind of initial processing is done to the data? I thought you get the golub.RData under the /multtest/data directory by running golub.R script that is attached(in the inst/doc directory) but when I run that script on the original data, and do "golub[1:4, 1:4]" i cannot get the same thing as in the documentation, i get: Gene.Accession.Number call call.1 call.2 36 2.000000 2.000000 2.017033 2.000000 37 2.332438 2.064458 2.677607 2.190332 38 2.901458 2.636488 3.168497 2.618048 39 4.162505 2.788875 3.753506 3.685742 2- My other question is, why is the need to center, and to scale the data in the golub.R script, is it ever used? 3-Also in the same script, the class labels are initialized to 1, and 2(i.e. golub.cl<-c(rep(1,27),rep(2,11)) ) although all the statistical tests upstream require 0, or 1 as labels. Am I wrong? Is anyone running into similar problems. thanks.
