Hi,
I am using "multtest" to analyze proteomics data. The
experiment is to compare protein differential
expression between Wild Type and mutant cell types. MS
software generates a ratio of intensity of
heavy-isotope/light-isotope which correspondent to
wild type vs. mutant. It is a triplicate experiment,
but for some proteins, ratio data are missing. My R
script is very simple:
> dd<-read.delim("log2_data.txt", header=TRUE)
> clabel<-c(0,0,0)
> res<-mt.maxT(dd, clabel, B=20)
Error in mt.checkclasslabel(classlabel, test) :
in t test, every number in class label needs
to be 0 or 1 and neither of the 0 set or 1 set can be
empty set
The folllowing is your setting of classlabel 0
in t test, every number in class label needs to be 0

Could any one help?
Thanks a lot.
