Try changing:
sudo add-apt-repository -y "ppa:marutter/rrutter"
sudo add-apt-repository -y "ppa:marutter/c2d4u"
to:
sudo add-apt-repository -y "ppa:marutter/rrutter3.5"
sudo add-apt-repository -y "ppa:marutter/c2d4u3.5"

The R C API changed between R-3.4.x and R-3.5.x, which created
incompatibility in packages installed using different versions.  Any R
> 3.6.x should use the "ppa:*3.5" PPAs.
