How define global Variable?
Hello,
I try to define a global variable.
My example:
R> a <- "old"
R> test <- function () { a <- "new" }
R> test()
R> a # shoud be "new"
This doesn't work. I would like to modify the variable "a" in a
procedure. How can I do that.
Thank you for helping.

Problem with length of array while calling C from R
Hello,
my problem is that I don't know how long must be an array of double while calling C from R.
R-Code:
> array <- c(1,1,1)
> save <- .C ( "Ctest" , a = array )
C-Code:
void Ctest ( double *array )
{ ...
array = (double*) realloc ( array , new_number * sizeof(double) ) ;
...
}
The length of "array" will be compute in C.
At the end save$a has a length
