I'm trying to read data a program produces in matrixmarket array format
into R and its giving me fits. I've tried read.MM (below) and readMM (from
the Matrix package) but neither works. One of them says array format isn't
supported, the other reports something indecipherable about Fortran.
Here's the file contents. Can't get much simpler than that!
%%MatrixMarket matrix array real general
> %This file contains LIBFM global mean which is required for computing
> predictions.
> 1 1
> 1.786238830716e-02
Can someone please help? Seems such a simple problem.
