[R] Problem with workspace loading after languageR use

[Prof Brian Ripley]

The problem would appear to be something missing in R.  From what I can 
see you have saved a reference to a package environment in your workspace. 
When load() tries to resolve this, it calls findPackageEnv and that does 
not exist in current R (or any recent version I looked at).

I think adding the following to your new session before load() will help

findPackageEnv <- function(info)
    as.environment(paste("package", "info", sep=":"))

will work, but if not try

findPackageEnv <- function(info) .GlobalEnv

If you send me the problematic workspace (or reproduction instructions) I 
can take a closer look.
