Hello, I got a question with the R function constrOptim.

>From the R help, it says that the return values of "constrOptim" are the
same as "optim". For the return value "convergence" of the function
"optim", the values should be 0, 1, 10, 51 and 52. See

When I use constrOptim, I get "convergence" values 7 and 11. What do they
mean exactly?

Thanks again,

Shuangge Ma, Ph.D.
