I am quite new in R, I looked at R manual- how to build R Package, 
still not very clear. Yes, it would be very helpful if I could 
download a package having Fortran source codes to look at, Do 
you know any package built with Fortran source code? Thanks!

You need to setup a Makevars.win and at lest modify 
and probably 
depending on how you link to the DLL. 

I suggest downloading example packages from Bioc / CRAN to look at.

We have several projects in the center done by researchers over years 
in Fortran, there are copy right issues etc to prevent us from 
giving away the source codes, but a lot of social scientist are 
interested to use the program. We tried to use dlls to make plugins 
(available in our website) in various statistics platforms 
(SAS, STATA and R) to make it available to general public. 

We used to be able to build R package using dll on version R-2.7.0, 
, but failed to build with newer R version with the same source. 
Any help is greatly appreciated. 

When I try to build R package for newer version of R, I could build 
to get "lcca_1.0.0.tar.gz", but when I "R CMD check lcca_1.0.0.tar.gz", 
I got error message as:

and the message in 00install.out is:

Thanks a lot!
