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.

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.

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. ====> install.packages("aod",repos='https://cran-archive.r-project.org/bin/windows/contrib/3.0/') Warning in install.packages : unable to access index for repositoryhttp://cran.rstudio.com/bin/windows/contrib/3.0 Warning in install.packages : unable to access index for repository https://cran-archive.r-project.org/bin/windows/contrib/3.0/bin/windows/contrib/3.0 Warning in install.packages : package ?aod? is not available (for R version 3.0.3) On 2020/10/5 ?? 04:12, Uwe Ligges wrote:> 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.
