Hello all,
I have develop a small package with C code. The package works well with 
R-1.9.1 on windows and mac os x. One colleague has install R 2.0.0 on its 
mac and the cocoa interface. The library works well in terminal or aqua-gui 
version, but not with the cocoa version. I have to test what is exactly the 
problem, but I am quite sure that the problem is with the C code. The 
functions works well but the C code does not transform any of the 
arguments. The call is something like:
.C("myfunc", res=as.double(rep(0,n)), x=...). The vector res must be 
transformed by the C function but nothing happens.
What is very strange is that it happens only for the cocoa version.
I would like to know if others have encounter this kind of problems. I 
will  test different things to be more informative and produce a better 
description of the problem
