odd behaviour when colouring based on a numeric vector about colourvalues

Yes, that's unexpected. The numeric v is returned scaled [0,1] , so I might need to put a clone() in there somewhere.

But that doesn't explain why the integer works though.

I'll investigate tomorrow

Ok, a bit of digging,

All my Rcpp method signatures for "numbers" are Rcpp::NumericVector. So, when passing in an integer vector (from R), it has to be coerced to a NumericVector, thus a copy is made, and hence the difference between the integer and numeric results.

Thanks! Just tested and behaves as expected now.
