[Rcpp-devel] Using spatstat in Rcpp

[mohammad ghorbani]

Hi there,

I would like to call discpartarea() and as.owin() functions of spatstat from Rcpp. In a simple example 
consider the following C++ code in which I'm trying to access the above  functions:

#include <Rcpp.h>
using namespace Rcpp;

// [[Rcpp::export]]
NumericVector IndepSelfCortCpp( NumericMatrix obsu) {
  NumericMatrix obsxy = obsu( _ , Range(1,2) ) ;
  NumericVector xyW= NumericVector::create(0,56,0,38);
  double rslt = 0; 
  
        rslt= spatstat::discpartarea(obsxy, 0.1, spatstat::as.owin(xyW));
  
return (rslt);
}
/* ** R
obsu <- matrix(c(0.5, 1.5, 4, 12, 1,2,3,4,2,3,5,7), ncol=3)
IndepSelfCortCpp(obsu)
*/


When I source the file in Rstudio with  sourceCpp(), I get the error:" 'spatstat' has not been declard "

I was wondering, a direct call  a function of an R package like spatstat is possible from Rcpp.
If yes, Could anyone help me on debugging the code? 

Best Regards,
Mohammad Ghorbani






 

I was wondering is it possible to call
