Hi Duncan:
Thank you for your help last time, since I do not use NULL to indicate
empty enviroment, I think I'm fine.
And yes, I did upgrade my R version recently, but how comes I still get this
warning for new files created
and saved after that update ? Is there anyway to get rid of this message ?
Thanks a lot .
best
