[R-SIG-Mac] Calling Objective C/Cocoa code from R

[Guillaume Chapron]

Hello,

I have a simulation model (command line tool) written in Objective C/ 
Cocoa. I would like to know if it is possible to call it from R and  
get the results into R as well. The documentation explains how to do  
it with C or Fortran, but I have not found anything with Objective C/ 
Cocoa. Has anyone tried do this or do you know an example explaining  
how?

Thanks

Guillaume
