The files were saved in an earlier version of R, which used NULL to
indicate the base environment. R is telling you that NULL is not a
legal environment. It should be automatically converted to baseenv().
In a number of cases, people used NULL to indicate an empty environment
(even though there was no such thing when NULL was used); if that's true
for your code, then you'll need to fix it. emptyenv() now gives you an
empty environment if that's what you really want.
