Okay, so it's not an RStudio issue. However, I'd guess setting
options(repos = "https://cran-archive.r-project.org";)
at the start of your session could make everything work. (I'm guessing
you currently have it set to "http://cran.rstudio.com";, which is the
source of the last warning below, probably due to an R bug. But since
you're using an obsolete version of R, it shouldn't surprise you that it
has bugs that nobody else is seeing.)

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.

Just remembered: RStudio runs its own wrapper around
install.packages(). Steven, you should try doing the install from
outside of RStudio, and see if it makes a difference.

He didn't specify the RStudio repos, though it's probably implicitly
specified in getOption("repos"). I wonder why install.packages() is
looking there, when repos is given explicitly?

Thanks. I did as suggested but still received a warning, though the

What is 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.
