Hi,
At the outset I would like to thank the developers of rcpp for this
wonderful tool. My question
is elementary but I am posting it here only because on stack exchange I see
Dirk suggesting that
this is a better place to get replies.
Thanks again
Bharath

Description of problem:
--------------------------------
I tried a very simple example from Hadley Wickham's website and it worked
https://github.com/hadley/devtools/wiki/Rcpp
cppFunction('
double sumC(NumericVector x) {
int n = x.size();
double total = 0;
for(int i = 0; i < n; ++i) {
total += x[i];
}
return total;
}
')
Then I try an example written in a c source file from
http://dirk.eddelbuettel.com/blog/2012/11/14/
and source it and get compilation errors
test1.c
------
#include <Rcpp.h>
// [[Rcpp::export]]
Rcpp::DataFrame mypnorm(Rcpp::NumericVector x) {
int n = x.size();
Rcpp::NumericVector y1(n), y2(n), y3(n);
for (int i=0; i<n; i++) {
// the way we used to do this
y1[i] = ::Rf_pnorm5(x[i], 0.0, 1.0, 1, 0);
// the way we can do it now
y2[i] = R::pnorm(x[i], 0.0, 1.0, 1, 0);
}
// or using Rcpp sugar in one go
y3 = Rcpp::pnorm(x);
return Rcpp::DataFrame::create(Rcpp::Named("Rold") = y1,
Rcpp::Named("Rnew") = y2,
Rcpp::Named("sugar") = y3);
}
commands:
---------
sourceCpp(LIB.PATH %+% "test1.c",verbose=TRUE)
