[R] Cannot load library(glmulti), because: Error: package ‘rJava’ could not be loaded

[Bruce Ratner PhD]

Jeff:
Just want to follow up to thank you. All's good. Up and running. 
FYI: I thought I had Java because SAS needs Java. 
Unbeknownst to me, SAS changed over to their own "Java." 
So when I got that error message of "no rJava" I was confused. 
Thanks so much for your earnest reply and trouble shooting. 
It does not go unnoticed.
Bruce
