Dear Rcpp experts,
When passing a vector/argument with infinite values to a C++ function,
the R wrapper returns NA's. [See the code below] Is there a way around
this to ensure that infinite values are preserved from R to C++ and then
from C++ to R again?
######################################
D <- matrix(c(0,1,Inf,Inf),2,2)
src3 <- '
IntegerMatrix xD(D);
IntegerVector Drow(xD.ncol());
for(int i=0; i<xD.ncol(); i++) std::cout << xD[1,i] << std::endl;
return xD;
'
rowExtraction <-
cxxfunction(signature(D="matrix"),body=src3,plugin="Rcpp",verbose=TRUE)
rowExtraction(D)
######################################
Thank you very much,
Cedric
