I have 72*7130 golub microarray dataset. I apply Dudoit pre-processing step in matlab and save txt file.

ın R, I use this code;

disc <- read.table("C:/Users/Desktop/leuk.txt", header=F, quote="\"") library(discretization)

values=disc[,-1] cancer_type=disc[,1] data1=data.frame(values,cancer_type)

library(discretization) chiM(data1,alpha = 0.05)

But,last code doesn't work. What is the problem ?
