I don't think there is a cbind-equivalent in Rcpp, but you can do
cbind1 <- cppFunction("NumericMatrix cbind1 (NumericVector x, NumericVector y){
NumericMatrix out (x.size(), 2);
out(_,0) = x; out(_,1)=y;
return out;
}")
cbind1(1:5, 2:6)
[,1] [,2]
[1,] 1 2
[2,] 2 3
[3,] 3 4
[4,] 4 5
[5,] 5 6

Subject: [Rcpp-devel] cbind column(s) or rbind row(s) to a NumericMatrix
Is there a way to cbind column(s) or rbind row(s) to a NumericMatrix in Rcpp?
I have made a NumericVector that is the same length as the number of rows of a
NumericMatrix, and was wondering how to (c)bind them together.
Thanks
HLM
