Hello all and Prof. Brian Ripley ,
Sorry about my incautiousness, I use the tips, but is happen same problems.
Below the R code.
################################################################
rspcplot <- function(file1="dg_01.lab.txt"){
if(is.null(n))
stop("You need first run the function cluster")
file<-"dg_01.lab.txt"
aux<-file1
file1<-pmatch(file1,file)
if(is.na(file1)){
matrix=loadMatrix(file,n)
}
else{
matrix=loadMatrix(aux,n)
}
matrixc<-correct(matrix)
#merge2(matrixc)
nrow=nrow(matrixc)
ncol=ncol(matrixc)
ntemp=getTemp()
out <- .C("merge2",matrixc,nrow, ncol,ntemp,outMerge=as.integer
(0),outHeight=as.integer(0),PACKAGE="rspc")
##########################################################################
Below the C code.
##########################################################################
void merge2(int *nmat,int nrow,int ncol, int *ntemp,int ntam, int *out, int
*height){
int row,col,*temp,i,j,k,n3,tam,x,aux2,n1;
row = nrow;
col = ncol;
int *temp1,*temp2,*temp3,*temp4;
temp1 = (int*)Calloc(col,int);
printf("OK1 \n");
temp2 = (int*)Calloc(col,int);
printf("OK2 \n");
temp3 = (int *)Calloc(col,int);
printf("OK3 \n");
temp4 = (int *)Calloc(col,int);
if(temp4 == NULL){
printf("\n\n No Memory4!");
exit(1);
}
printf("OK4\n");
int *cvector;
cvector = (int *)Calloc(col,int);
if(cvector == NULL){
printf("\n\n No Memory5!");
exit(1);
}
printf("OK5\n");
tam=ntam;
#######################################################################
Output of Work Space:

Error in rspcplot() : Calloc could not allocate (145869080 of 4) memory

Using the Ruspini data, the values of variables col = 2 and row = 75. I was
thinking that the number of pointers and space of memory are too big.
Thanks All !
