[R] Warning from installing packages in R3.6.1

[Steven Yen]

Hello Duncan:
Below I am sending
(1) message from installation of a .zip file;
(2) from installation of aod from CRAN;
(3) from running the line sessionInfo()

Looks like both installations were successful despite the warning 
message. Now the point seems to be to figure out why the warning arises. 
Thank you.
Steven Yen
