Did you take a look at the error message when you try to install curl?
This is because all these packages depend on curl, which in turn
requires curl-devel. You may install curl-devel in your system and
then try again.

Yet another posibility now for you is:

sudo dnf copr enable iucar/cran
sudo dnf install R-CRAN-DMwR

That's a Fedora repo I maintain with nearly 15k CRAN packages. Not the
entire CRAN, but close enough.
