Yes, it does. It's due to cedta. If you put the following into the datatable-test.R file, you'll find that the top environment (topenv) is not R_GlobalEnv as needed for cedta to work right. I'm not sure of a fix or workaround. print( topenv() ) - Tom print(topenv()) _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
