...;c" and limits to p1 and p2 probabilities (Consumer and Producer). The optimize I could define only using the p1 point, because the "n" and "c" values, are integers and I couldn?t run the example like in mathematica. Could anyone help me Thank you very much.

I want to create a vecor with frequencies. I have tried this: a <- c(1,1,1,1,2,3,4,5,5) b <- table(a) print (b[1]) which results in: > print (b[1]) 1 4 The only thing I want is the 4. So this seems obvious: print (b[1,2]) but it does not work: Error in b[1, 2] : incorrect number of dimensions How do I get a vector or how do I refer to the "4" without getting the

...le size) c , (critical level of defectives) alpha , (producer's risk) betha , (consumer's risk) p2max (consumer's probability p2) Could one help me understand how can desing the optimize nonlinear function using R for two binomials or point me some tips? Thanks in advance. EToktar

...solving nonlinear unconstrained minimization problems. May I wrong, but the nlm() function would be appropriate to solve this problem, is it right? Can I get a pointer to solve this problem using the nlm() function or where could I get some tips/example to help me, please? Thank you very much. EToktar
