The authors of legend() have not responded AFAICS.

It is possible to pass some integers, but 'pch = c(-1, 3, 4)' is not explained. Strangely although ?points documents the interpretation of both positive and non-negative integers, legend() excludes negative ones.

I'll correct the docs, at least.

Thank you for the report.
