[R] NLMINB convergence codes

[Rebecca Sela]

According to the R documentation for NLMINB, the returned value of convergence is 0 for successful convergence.  When I got another code (1), I looked up the PDF that linked from the documentation (http://netlib.bell-labs.com/cm/cs/cstr/153.pdf), which said that a return code under 3 was impossible.

Is there other documentation that gives the correct meanings of the NLMINB convergence codes in the R implementation?

Thanks!
