Hello all,
I am looking at the one program of the marketing textbook. I understand what
the following function is doing especially the .C command
Can someone help?
If I take off the .C comand will it still run??
drawwc = function(w, mu, y, sigi) {
.C("draww", w = as.double(w), as.double(mu), as.double(sigi),
as.integer(length(y)), as.integer(ncol(sigi)), as.integer(y))$w
