in reply to multidimensional array in Statistics::R

Looking at the docs, it seems like you'd have to set one vector of the multi-dimensional array at a time.

Something (untested) like this:

... $R->set("mat[$_]", $mat[$_] ) for 0 .. $#mat;

But you probably need to tell R that 'mat' is a matrix first by preceding the above with something like:

mat=matrix(1:12,3,4)

Or perhaps a data.frame with named columns would be a better choice. See the R docs.

    I ended up splitting my data into individual vectors and then combining them in R. Yes, it'd be nice to load directly into a "data.frame" but it's not too much bother to do it on the R side.

    This whole thing was just because my data was so nicely packaged from the database (via fetchall_arrayref) and it seemed a shame to split it just to stitch it back together.

    Thanks. Good to see that it wasn't just some obvious thing I'd missed.
