To do so, I tried to install the package Rcplex on my computer (Windows7-64), so I did the same as installation Instructions<http://www.geeklog.net/docs/english/install.html> and edited the file "Makevars.win" by adding the path "C:/Program Files/IBM/ILOG/CPLEX_Studio_Preview124/cplex/include" (where the trial version o...

Dear R-experts, this is not a direct R-problem but I hope you can help me anyway. I would like to minimize || PG-I || over P, where P is a p x p permutation matrix (obtained by permuting the rows and/or columns of the identity matrix), G is a given p x p matrix with full rank and I the identity matrix. ||.|| is the frobenius norm. Does anyone know an algorithm to solve such a problem? And if
