Dear Roger,

How is Matrix loaded?

If you use sparse.model.matrix() inside a function from your package you
need to declare it as Matrix::sparse.model.matrix()

Best regards,

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
