Dear Dr. Ripley,
Or possibly other people on the list.
I'm using the R v1.11 on Macintoch
Unlikely. There is no R v1.11, and R 1.1.1 (following the most common
misspelling) wasn't available for the Mac.
and I seem to have a problem with the
function R_alloc. It crashes when using the following .C function (only an
example):
///////////////////////////////
# include <R.h>
void Hello(int *n)
{
int i,x;
for(i=1;1< *n ; i++)
This is an infinite loop. You probably mean i<*n as the second
expression, or perhaps i<=*n (did you want n or n-1 repeats?)
{
Rprintf('salut!!!\n');
This is invalid C, as your compiler should have told you. You need double
quotes.
}
x = (int *) R_alloc(5,sizeof(int));
x was declared as int, not int *, so again this is invalid.
}
///////////////////////////////
I call it in R with this line:
.C('Hello',as.integer(5))
Any idea why and how I can resolve this problem?
After fixing the C errors and in a version of R that exists (2.0.1) I get
dyn.load("hello.so")
.C('Hello',as.integer(5))
salut!!!
salut!!!
salut!!!
salut!!!
