Thank you, Ben; corrected in my (not yet committed) development
version.

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*.

Best regards,
Martin

Hi, Martin, Ben, et al.:

 ????? 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
