Hello R,
To analyze multi-level data, I started learning and using lmer. So far
so wonderful. I then found some useful functions in package languageR.
But then the following problem ocurred: Whenever I load and use the
languageR package, then save the workspace - or quit R with saving the
workspace - I am unable to reload that workspace in a later session.
That is, R doesn't start at all when I try to start it by clicking the
workspace file.
Loading languageR before loading the workspace doesn't help, but yields
the message:
Error in load("D:\\statistics\\MultilevelAnalysis\\.RData") :
could not find function "findPackageEnv"
Thus, the saved workspace remains inaccessible. I not 100% certain that
languageR is the scapegoat, but my trial-and-error experiments indicate
it is.
My system is Win XP Home/Professional:

[R] Problem with workspace loading after languageR use
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.
