R help - Oct 2008 - Sampling

Hi Guys,
I am in desperate need with sampling. I am suppose to sample from a dataset.
I use the following code:
> for(i in 1:5){temp[i]<-sample(T2,40,replace=F)
+ show(temp)}

but all the samples are the same, but I want them to be different.any
suggestion? 

Thanks

Yes.  Read the posting guide.

(a) Your example is not reproducible.  What is T2?  How is temp
initialized?

(b) In the assignment temp[i] <- sample(T2,40,replace=FALSE)
you are attempting to assign a vector of length 40 to an object
of length 1; that can't possibly work, now, can it?  It should
give you warning messages.

(c) I really can't figure out how you're getting ``all the samples are
the same''.  Things go wrong, but not that.

Tell us what you *really* did.

	cheers,
