Both the official R documentation and Wolfgang's paper in the Journal of Statistical Science describing this (extremely useful) package, name the control variable for maximum iterations in numeric model fitting as 'maxiter'. The correct name is 'maxit'. A small point concerning an (I guess) infrequently used bit of functionality, but this may help save someone an hour or so's head scratching!
