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.

Best,
Uwe Ligges
