[R] extracting more information from optim in R?
Dear All, I am in the process of translating some of my functions into C and one such function sometimes get stuck when I applied optim. The pure R codes work fine but the translated C codes occasionally get stuck and I like to find out why. Is it possible to extract the parameters of function calculated in each step of the Nelder-Simplex algorithm, the trace option only produce the value of the objective function in each iteration? Is there a simple way to extract this information? Any help greatly appreciated. ### Assistant Professor Steve Su School of Mathematics and Statistics Faculty of Engineering, Computing and Mathematics M019, 35 Stirling Highway Crawley, 6009, WA, Australia Phone:+6164883369 http://www.uwa.edu.au/people/steve.su CRICOS Provider Code: 00126G [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
