[R] Is there a tool to find unused functions?

I've inherited a large R codebase which has grown over a few years and a
few different developers.
It contains many things I'd like to delete:
- Unused functions
- Variable definitions that are never called
- Unreachable code
I'd write that myself, it would even be fun, but I don't want to
reinvent the wheel.
Is there an R package that can find these things?
I've heard of lintr, but I'm not sure if it's the right tool, since,
unfortunately, the code is in a folder (not a package) with many R files
that are sourced from one master file and lintr can only check a single
file or an actual package, from what I understand. A workaround of
course would be to concatenate all files into one R script.
I'd appreciate any hints on how to best solve this.
Thanks in advance,
