Hi, I am a beginner-class use of the amazing Rcpp. I am using to simulate
finite state Markov chains.
Previously all the c++ function I wrote were working perfectly. I compiled
all my functions in package and they work fine.
But now after I updated to Rcpp 0.10.3, whenever I sourceCpp, it throws a
'unused arguement' error.
However when I use the all the functions to build a package, it works fine.
I think this is a really small problem, but its beyond my knowledge of c++
Any help will be greatly appreciated.
Following are simple example codes and the error I am getting..
cppFunction('
+ int add(int x, int y, int z) {
+ int sum = x + y + z;
+ return sum;
+ }'
+ )
Error in Rcpp:::sourceCppFunction(function(x, y, z) { :
unused argument ("sourceCpp_94801_add")
Second example code
#include <Rcpp.h>
#include <iostream>
#include <vector>
// [[Rcpp::export]]
using namespace Rcpp;
using namespace std;
int mcfunC(int oldState, NumericVector states, NumericMatrix prob_mat){
RNGScope scope;
NumericVector newState(1);
int pixel = oldState;
Environment base("package:base");
Function sample = base["sample"];
newState = sample(states, Named("size", 1), Named("prob", prob_mat(pixel,
_)));
int state_new = newState[0];
return(state_new);
}
Rcpp::sourceCpp('src/mcfunC.cpp')
Error in Rcpp:::sourceCppFunction(function(oldState, states, prob_mat) { :
unused argument ("sourceCpp_20302_mcfunC")
Thanks in advance.
