[R] help please

[osita k ezeh]

hello,

please can anyone help me out. Am a new user of R
program. Am having problem
with this code below, not getting the expected
results.

 Each m, the cumulative sum should be 1.000 but the
2nd and 3rd m returned 2.000 and 3.000
instead of 1.000.



thanks
Aruike
