I think that you need to check how MatrixModels imports
sparse.model.matrix(). If MatrixModels depends on Matrix, then you are
probably forced to depend on MatrixModels.

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.
