As usual, you can download the full source to find out what you want, but it's a bit hidden. Simply said, nnet (R+C) is part of package MASS is part of bundle VR, and can be downloaded as a tar.gz from http://cran.at.r-project.org/src/contrib/Descriptions/VR.html (No private flames, please, in case I should have mixed up package and bundle). /* nnet/nnet.c by W. N. Venables and B. D. Ripley Copyright (C) 1992-2002 * * weights are stored in order of their destination unit. * the array Conn gives the source unit for the weight (0 = bias unit) * the array Nconn gives the number of first weight connecting to each unit, * so the weights connecting to unit i are Nconn[i] ... Nconn[i+1] - 1. * */ #include <R.h> #include <R_ext/Applic.h> ______________________________________________ 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 and provide commented, minimal, self-contained, reproducible code.
