Dear maintainer,
You have file 'mrgsolve/man/mrgsolve_package.Rd' with
\docType{package}, likely intended as a package overview help file, but
without the appropriate PKGNAME-package \alias as per "Documenting
packages" in R-exts.
This seems to be the consequence of the breaking change
Using @docType package no longer automatically adds a -package alias.
Instead document _PACKAGE to get all the defaults for package
documentation.
in roxygen2 7.0.0 (2019-11-12) having gone unnoticed, see
<https://github.com/r-lib/roxygen2/issues/1491>.
As explained in the issue, to get the desired PKGNAME-package \alias
back, you should either change to the new approach and document the new
special sentinel
"_PACKAGE"
or manually add
@aliases mrgsolve-package
if remaining with the old approach.
Please fix in your master sources as appropriate, and submit a fixed
version of your package within the next few months.
Best,
-k
