Thanks, that helps! The visualization is very messy, because I have
about 100 functions, but foodweb() returns a matrix of which function
calls which, and the functions callers.of("myfunc") and
callees.of("myfunc") do exactly what I was looking for.

mvbutils::foodweb produces a graphical display of the hierarchy (or
network or ...) of function calls. Isolated functions are not called.
This might help you.

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,
Alex
