Hello Everyone,
I am trying to use NA_REAL, NA_INTEGER, and R_NaN in my CPP code(doesn't
use R main). When I compile and run my code,* NA_REAL* it gives the value
as *nan* and *NA_INTEGER* gives the value as *-2147483648, and R_NaN as 0*.
I used the following code(from Rcpp FAQ):
Rcpp::IntegerVector Missing_I() {
Rcpp::IntegerVector v(1);
v[0] = NA_INTEGER; // NA
return v;
}
Rcpp::NumericVector Missing_N() {
Rcpp::NumericVector v(4);
v[0] = R_NegInf; // -Inf
v[1] = NA_REAL; // NA
v[2] = R_PosInf; // Inf
v[3] = R_NaN; // nan
return v;
}
When I compile the functions using sourceCpp() I get the output as expected:
> sourceCpp("~/R/RcppDeepState/inst/extdata/filesave.cpp")
> Missing_I()
[1] NA
> Missing_N()
[1] -Inf NA Inf NaN
But when I compile the code using the TestHarness it gives me the following
output:
missing_n values: -inf nan inf 0
missing_i values: -2147483648
I saved the above functions(Missing_I, Missing_N) in a header file and made
a call to those functions from the testharness:
TEST(deepstate_test,datatype){
RInside();
Rcpp::IntegerVector missing_i = Missing_I();
std::cout <<"missing_i values: "<< missing_i << std::endl;
Rcpp::NumericVector missing_n = Missing_N();
std::cout <<"missing_n values: "<< missing_n << std::endl;
}
How can I get the results as expected? Any help is appreciated.
Thanks,
Akhila
