[R] for loops and counters

[Peter B. Mandeville]

I am trying to assign values to a vector (pvalue). Similar code works in C
but not in R. What am I doing wrong?

	r <- pvalue <- 0
	for(i in (1:(k-1))){
		for(j in (i+1):k){
			r <- r+1
			tstat <- (means[i]-means[j])/rms
			pvalue[r] <- 2*(1-pt(abs(tstat),df))
		}
	}

Thank you.

Peter B.
