Some (fatal) bugs which may kill interpreter should be fixed. In addition, user-visible changes are: * *.mes, *.pro files are not created if name=NULL(this is default) in donlp2(). * use machine-epsilons defined in R for internal calculations(step-size, etc.). * numeric hessian is now evaluated at the optimum and calculated with the algorithm specified in 'difftype' in donlp2.control(). Setting difftype=2 will produce (roughly) same value as optim() does. I sincerely appreciate users who sent me useful comments.

[R] Rdonlp2 - an extension library for constrained optimization
Hello R-lists, I have created an extension library called Rdonlp2. This is a wrapper for Peter Spellucci's DONLP2: http://plato.la.asu.edu/donlp2.html DONLP2 is a standalone C program that can solve following minimization problem: min f(x) subject to * parameter bounds * linear (equality) constraints * nonlinear (equality) constraints Rdonlp2 is a bridge over R and DONLP2, that is, you can execute the constrained optimization with R function and objects and get detailed outputs from DONLP2 as R objects. Some tutorial, source code, Windows binary, OSX binary are available from: http://arumat.net/Rdonlp2/ The package contains the tutorial as PDF, and 4 demo scripts. Any comments or suggestions are welcome.
