snow: export data inside function and check worspaces

Hi

I have two questions for package snow:

1 How do I export object defined within a function with clusterExport()?
snow use get("object", env=.GlobalEnv) but the object within a function
belong to the function env and not globalenv if I understood well.

If you want to use clusterExport, I believe you would have to
first assign the value of the local variable to a global variable,
since that is the only thing that clusterExport will operate on.
You might want to consider other methods of handling that
data, though.

2 How do I check the objects sent? I tried clusterCall(cl, ls()) but gives
me character(0)

Try something like:

   clusterCall(cl, function() ls(globalenv()))
