Hi,
I couldn't get the rnorm() work right in C, for example, the following code
produce strange results.
#include
#include
int main(void){
double x[3];
for(int i=0;i<3;i++) x[i]=rnorm(0,1);
printf("%lf,%lf,%lf",x[0],x[1],x[2]);
return 0;
}
output : -8.773321,-8.773321,-8.77332

I've wondered about this sort of thing too. Are there any successful

A possible solution is to use strncasecmp instead of strncmp
in function
In session of R, occour following bug's in de (data.entry) function.
*** caught segfault ***
address 0x2c, cause 'memory not mapped'
Traceback:
1: dataentry(odata, as.list(Modes))
2: de(..., Modes = Modes, Names = Names)
3: data.entry(posto, fecha, serie = registros, status)
4: onEditaSeri
