[Rcpp-devel] Inf to NA.

[Cedric Ginestet]

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
