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.

1. 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.

2.  to get the LCL(m) and UCL(m) for each m base on these instructions
         if out.cum > 0.025 then LCL(m)= y-1
         if out.cum >0.975 then ucl(m)= y-1
   how do I code these instructions into this code.

thanks
Aruike
