Dear R Users I would like to use optim function to optimize a function. I read help but I couldn't find what I need: is it possible to get information after each iteration, for example as there is in MATLAB: Gradient's Iteration Func-count f(x) Step-size infinity-norm 0 24 388.976 14 1 72 385.67 0.0292637 16.8 2 96 383.54 1 4.15 3 120 383.412 1 0.108 4 144 383.412 1 0.002 5 168 383.412 1 0.00149 6 192 383.412 1 6.23e-005 7 216 383.412 1 1.01e-005
It is useful when iteration takes long time - I know what's happen I would appreciate any suggestion Robert ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
