Hi,
I have written small code in C++ using Armadillo and inline with
RcppArmadillo package.
The input is data.marix(X). Some cells might be NAs. Example in R: X =
matrix(sample(c(rnorm(10*9.9),NA)),ncol=10)
I am calculating conditional correlation on columns of that matrix, just
picking vectors,
NA, NaN or Inf

Can you provide an example how to convert Armadillo colvec to uvec vector
which I assume works as selector for rows?
Thanks

I am not running R's cor(..) function. I am calling arma::cor(...) on two
vectors. I cannot use R's function, because I have some nested loops and
extra steps before calculating Pearson's correlation.
The only thing I am providing in R is the matrix with values and matrix
with zeros and ones where

I already solved my problem, but I don't want to continue since it's off topic.

Hi,
I would like to implement algorithm which works on 4 or more dimensional
array. Is it possible to have full support of R arrays in Rcpp ?
Thanks
