K means algorithm C code
Dear R user,
How can I get the C or C++ source code of the "R_kmeans_MacQueen" or
"R_kmeans_Lloyd" subroutines implemented in the R "kmeans" function of the R
stats-package {stats}? Would these be available as a C header file (*.h)
somewhere from the R installation???
Any help to get a C or C++ implementation of these clustering algorithms
would be very welcome.
Thanks for...
