Dear all,
I am still learning R with write a small function for my self.
I was wondering if someone can help me to write a R function formula below:
Z_k (x) = \sum_{i=0}^{i=k} \binom{n}{i} (m-1)^i
Thanks a million in advance,
Sincerely,
Jan Sabee

What is "m"? Your Z_k is a function of "x" and there is no "x" on the RHS. Are you trying to re-write "pbinom"? --sundar
