No. You should be doing this in your C/C++ code.

Dr. Ripley,
Thanks for your answer, I guest the key is that
in my code R can't know tmp is being modified.
I couldn't find a duplicate function for the
R environment. Is there any ?

Without seeing your code for the .Call parts it is impossible for us to
know, but as .Call does not duplicate its arguments (unlike .C), it is
possible for it to change both tmp and a copy of tmp, tmp.last.
So it seems likely there is a bug in your C code if that is not your
intention. The norma
This is the general outline of my code::
main(argc,argv){
...
Rf_initEmbeddedR(argc,argv);
...
Test_tryEval("source(test.r)");
...
}
#
# test.r
#
...
dyn.load("toload.so")
tmp <-matrix(data=1,nrow=narray*2,ncol=nclust)
.Call("Init",tmp,...)
while(...) {
