What I would do (and I think a lot of people
on this list) is to type:
colnames(B)
to see why 'sample' might not like it. There are
debugging tools in R, this seems like a good
opportunity to use them.

HI,
I have a file named "s1"(which has 14 rows and 4 columns) which is in csv
format. I import and call it "A" the file using:
A <- read.csv(file="s1.csv",head=TRUE,sep=",")
then I transpose it and call it "B"(which will have 4 rows and 14 columns)
using:
B=t(A)
when I want to make 5 samples from "B" (choosing 10 columns) using:
result=replicate(5,B[,sample(colnames(B),10)],simplify=FALSE)
I get the following error:
"Error in sample(colnames(B), 10) : invalid 'x' argument"
anyone has any idea,why?and how to fix it?
Thanks
