Dear R-devel members, The question: Is it possible to initialize and later free a large data structure strictly within a shared C library, to be used by a function in the C library that I'll call from R--without ever having to pass data to and from R? This is analogous to C++ object initialization/use/destruction, but if possible I'd like to stay in C. The context: I'm implementing

Hello R-people, I have searched the mailing list messages and the R site (through the web search and google) I didnt find anything related to Particle Swarm Optimization (PSO) for R. Is there a package that implements such algorithm? Thanks in advance, Ulises

Dear R users, I would like to draw your attention to 'cec2013', a new package providing R wrappers for the 28 benchmark functions defined in the Special Session and Competition on Real-Parameter Single Objective Optimization at CEC-2013 (http://www.cec2013.org/). The focus of this package is to provide an open-source and multi-platform implementation of the CEC2013 benchmark functions,

Dear R developers, Due to the increasing use R in hydrology and other close-related environmental sciences, I would like to ask if it would be possible to create a new Special Interest Group mailing list, called 'R-sig-hydro', specially devoted those topics. If possible to do so, I'd offer myself to maintain such mailing list (if needed). Thanks in advance, Mauricio

Dear list, I have a question related to the correct interpretation of the relative convergence criterion used by 'optim'. In the help of the function is it written that: "reltol:Relative convergence tolerance. The algorithm stops if it is unable to reduce the value by a factor of reltol * (abs(val) + reltol) at a step." and I was wondering if the previous criterion is
