It's easy enough to load scalers and simple arrays into R through Statistics::R but I'm having trouble with multidimensional arrays. The manual doesn't actually claim to support this but maybe someone has managed.

Arrays are passed to R by reference (to make a simple list in R). Passing a reference to a multidimensional array produces a list of array tags. For example:

`use Statistics::R;
use Data::Dumper;
my @arr = qw(foo bar baz);
my @mat = (["fred", "barney", "pebbles", "bambam"],
["george", "jane", "elroy", "judy"],
["homer", "bart", "marge", "maggie"]);
my $R = Statistics::R->new();
$R->set('arr', \@arr);
$R->set('mat', \@mat);
my $r_arr = $R->get('arr');
my $r_mat = $R->get('mat');
print "Array:\n", Dumper($r_arr);
print "Matrix:\n", Dumper($r_mat);
`

produces:

`Array:
$VAR1 = [
'foo',
'bar',
'baz'
];
Matrix:
$VAR1 = [
'ARRAY(0x7fdbf4007328)',
'ARRAY(0x7fdbf4014b80)',
'ARRAY(0x7fdbf4014c58)'
];
`
