BTW, there will be another improvement there, deprecating 'giveCsparse = TRUE' and replacing it by 'repr = "C"' the latter allowing all three kind of sparseMatrix formats ("C", "R", "T") instead of just Csparse* and Tsparse*.
How I can learn more about this, including (a) 'repr = ("C", "R", "T")', (b) how it creeps into my code, and (c) when I can expect to see it?
I'm running R 4.0.2, and "?sparse.model.matrix" on a fresh session generates "No documentation for ‘sparse.model.matrix’ in specified packages and libraries", but it's there after "library(Ecfun)". I find that interesting, because "Matrix" does not appear in the Ecfun DESCRIPTION file. AND I don't see 'repr = ("C", "R", "T")' in the "sparse.model.matrix" help file I do see.
Thanks, Spencer Graves
