There is a book titled "The R Inferno" with lots of debugging tips for
R: https://www.burns-stat.com/documents/books/the-r-inferno/

Start with a traceback(). Which function gave a matrix to the ||
operator (which accepts only logical scalars)?

If traceback is not enough, use options(error = recover). Once the
error happens, you will be able to inspect local variables inside any
of the active call frames, which may help understand where did A come
from and why it was given to the || operator.

Good luck!
