[R-pkg-devel] Error creating union class: object ‘.__C__compMatrix’ not found

[renozao]

Thank you William for the reproducible example.

Currently I using the following (same as in William's example):
setClassUnion("mMatrix", c("Matrix", "matrix"))

Martin, are the changes made in the union class handling affecting the way we should declare them?
Thank you.

Bests,
Renaud
