Thierry,
I have this:
if (require(MatrixModels) && require(Matrix)) {
X <- model.Matrix(Terms, m, contrasts, sparse = TRUE)
in my function rqss() I've tried variants of requireNamespace too without
success.
If I understand properly model.Matrix is from MatrixModels but it calls
sparse.model.matrix which is part of Matrix, and it is the latter function that
I'm
not finding. Maybe I should go back to the requireNamespace strategy again?
