Dumping my data in a post may not be such a good idea, since it involves a 10,000x100 array/matrix.

I'll give you a hands-on example though:

%myHash = (var1 => [1,2,3,4,5,6],
           var2 => [11,12,13,14,15,16]);
[download]

is what I've got, and this is what I would like to have:

@myArray = ([1,11],
            [2,12],
            [3,13],
            [4,14],
            [5,15],
            [6,16]);
[download]

which of course would be converted to a data.frame in R (which is not part of the question, but I would of course be really thankful for fast and efficient Perl -> R code too).
