The RExpression matrix was created solely to pass a matrix to another
RExpression actor. It is NOT a Kepler/Ptolemy matrix, so the Ptolemy matrix
viewer is not expected to work. Converting an R matrix to a Ptolemy matrix on
output would solve this problem but would be quite inefficient if the output
was just going to another RExpression actor where it would have to be converted
back to the R format.

Note I am not suggesting that an R matrix display would not be useful, just
that it is tied into the whole issue of format of data passed between actors.
