CRAN packages using uninitialised values
From Prof Brian Ripley on Mar 7, 2021:
All of these are from within the package and using values which were never initialized or already freed. Some are showing other issues which look a consequence of this.
Please correct as soon as possible and before Apr 7 to safely retain the package on CRAN.
