On failure (negative return codes), by default, it throws an exception (see Exceptions, below). In older versions of R, the corresponding nloptr version tries to install NLOpt from a broken link BTW, while the warning message at the end has nothing to do with the inability to install packages, it is a clear problem that needs to be resolved for you to have "normal" functionality as you learn R. In this article, we present a problem of nonlinear constraint optimization with equality and inequality constraints. Using alternative optimizers is an important trouble-shooting tool for mixed models. Can't install nloptr package for R, which is a dependency for lme4 package that we use for fitting statistical models. I have a problem formulated for NLOPT in R. 04.
