NA printing
Hi.
I'm writing a print method for an object that includes a numeric matrix
for which
the lower diagonal elements are not meaningful. So I make the lower
diagonal of my matrix NA and print it.
But my co-author does not like NA there and wants a dash.
I have tried coercing the matrix to character, essentially by
M[is.na(M)] <- "-" but this interferes with the pleasing
column
