And does ChrL-internal.r contain just one line as you said before, i.e.
.ChrL.env <- new.env()
?
If so, how have you determined that .ChrL.env does not exist? Names
that start with a "." don't show up in ls() listings by default. You
can't use exists() to test for .ChrL.env in either of the other files,
because they are probably sourced before it is (depending on the
collation order). It won't exist when you run them, but it will exist
in the package namespace when you load the package.
