Dear R-users

I am slowly migrating my mex files (MATLAB - Fortran and C) to R.  To get my
own functions available on R section I have decided to learn how to build  a
R package. I choose a simple example with a few Fortran and R functions
(wrapper).

The fortran sources are located at src and the R functions at R (as
recommended).  The building process went ok but R CMD check did not. The
error mgs was

Error in dyn.load("fortran.so") :
  unable to load shared object
'/home/eduardo/R_packages/test.Rcheck/fortran.so':

Although I can see that R cannot find the compiled fortran code I do not
know what to do.   I believe it is something to do with the following lines
in  the R-wrapper file

if (!is.loaded('calnpr'))
                   dyn.load("fortran.so")

How to add the path so that once the package is installed the compiled
fortran code can be found?

Many thanks

Cheers

Ed
