.Call and Segmentation Fault
Hello to everyone!
I use .Call to call a C function without arguments wich calls a
fortran optimization package. My C function uses others C and Fortran
functions and it works fine when I call it from a main() in a C
program. But when I call it from R with
.Call("name_of_the_c_function"), R gives me some weird output.
This weird output is a worng answer to my optimization problem

kmeans() compared to PROC FASTCLUS
...FORTRAN and
I'm not quite sure how to get at it. Has anybody looked into the differences
in the implementations or have any thoughts on the matter? Below is the code
I'm using in each case.
fit=kmeans(obs[,-1],centers,nstart=25)
*
proc* *fastclus* data=std maxclusters=*2* maxiter=*100* outiter drift
converge=*0.01* outseed=centers out=cluster;
var x y z;
*
run*;
Thanks,
Andy
