Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-recommended : Depends: r-cran-boot (>= 1.2.19) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Nonetheless, https://cran.r-project.org/bin/linux/ubuntu/artful/ is already available.
Edit: As asked by @muru in the comments, the output from sudo apt-get update
plus the output from sudo apt-get upgrade
were
