Hello, I had a question about calling some of R's fortran
routines from C.
Specifically, I would like to call: dqrfit from some C code
which will be
bundled as an R package. I was hoping someone knew of an
example in some
of R's code which does something like this (any fortran call
from R's C
would probably be a sufficient guide). So far I can only find
locations
where R calls the Fortran directly, but this is not an option for me.
Also, I am trying to gauge the overhead of making this call,
does anyone
have any knowledge of whether there might be some non-trivial
constant
time penalty on making such a call.
Thanks in advance, Jim
