[Rcpp-devel] Errors while compiling a script (seems to be related to Fortran)

Thanks for the comments. Suppose if I were to go with your third
suggestion, do you happen to have any examples of RcppArmadillo calling
SEXP functions that I can refer to?
In the past, I tried (1) putting the set of MASS functions in a separate
MASS.cpp file, (2) creating a header file MASS.h, and (3) making the main
script file call the MASS functions by doing include "MASS.h". But the same
errors were still present.
Thank you again for your help!
