Then you'd rather need
install.packages("aod",repos='https://cran-archive.r-project.org')
or use the contrib.url argument.

Thanks for the help. I do update to the latest R-4.0.2. As I said, for
reasons that's hard to explain, some of my tasks are better handled with
an older version of R, in this case R-3.0.3. Please just help me install
packages successfully with this older version of R.
I ran the following line but obviously was not getting it across.

From
../ReadMe
in the mentioned web resource:
"Packages for R >= 1.7.0 and R < 3.2.0 are available from
https://cran-archive.r-project.org/bin/windows/contrib/";
We do not hold binaries of several year old versions of R on CRAN.
Note that R 3.0.0 is 7 years old. You shoudl realy consider to update
to 4.0.2.

I had to install/use an older version of (R-3.0.3) for a reason. While
installing a package from CRAN (either in RStudio or R), I received the
following warning message saying unable to access index for repository
http://cran.rstudio.com/bin/windows/contrib/3.0. See message below. In
this case, I tried to install "aod". The install nevertheless went
through, as confirmed by the library statement (I did not try to use
it). Any idea? Thank you.
