In an RExpression, add an output port "out" and use this R script:

out <- matrix(c(TRUE, FALSE, TRUE, FALSE), 2)

I get [false] as the output token, which seems to be because RExpression.java on line 1108 says:

mt = new BooleanMatrixToken();

instead of:

mt = new BooleanMatrixToken(valS);

or something similar. I'm not actually sure such a constructor exists, but it seems like it should given the other constructors in the lines before.
