I am trying to download the “Formula” library using

Warning: unable to access index for repository

message: package ‘Formula’ is not available (for R version 3.2.2)
I receive the same message adding lib=<path> to the install.packages
call. An internet search suggests using download.file(), but that
requires knowing the url of the file in the repository. Can someone
tell me the url (just add Formula to the url above?) or suggest
another solution? Thanks.
I installed "Formula" just now, under R 3.2.2, using install.packages(),
with no problem. Did you have a *look* at the URL
https://cran.cnr.Berkeley.edu/bin/windows/contrib/3.2
???
Going there I see that the file Formula_1.2-1.zip is present and I was
able to download it by clicking on it.
So if you insist on using download.file() you could just tack
"/Formula_1.2-1.zip" onto the end of your URL. But there is really no
reason to do that; install.packages() works.
It is a mystery what your problem could be,
cheers,
