While trying to figure out how the Leaps package works, I came across this command:
qrleaps <- .Fortran("makeqr", np = as.integer(np), nn = as.integer(nn),
wt = as.double(wt), tx = t(xx), y = as.double(y), d = numeric(np),
rbar = numeric(nrbar), thetab = numeric(np), sserr = numeric(1),
ier = as.integer(0), PACKAGE = "leaps")
I understand that it uses a Fortran subroutine called makeqr
. I would like to locate this file and read its source code. Any ideas?
