[R] unable to access index for repository...

Thu Oct 8 17:54:09 CEST 2020

Thanks. You gentlemen please tell me what this means. In R (outside of 
RStudio) I ran:

install.packages("aod")

Received a warning (and installation did not seem to go through).

Then I tried

install.packages("aod",repos='https://cran-archive.r-project.org')

Received a warning but it went on to try

https://cran-archive.r-project.org/bin/windows/contrib/3.0/aod_1.3.zip

and it worked. See log below.

I expect to continue to use R-3.0.3 for a while and I very much like 
this to become a routine. Thank you all.
