pkgdown error

[RobinHankin]

Currently trying to implement pkgdown. Following commit 99eea7b (the result of executing use_pkgdown() and use_pkgdown_github_pages() I see the following error on github actions:

Attaching package: ‘permutations’

The following object is masked from ‘package:stats’:

    cycle

Reading man/Ops.permutation.Rd
Error in `build_reference()`:
! Failed to parse Rd in Ops.permutation.Rd
Caused by error in `UseMethod()`:
! no applicable method for 'replay_html' applied to an object of class "c('permutation', 'word')"

It's difficult to diagnose remotely, but I think the problem is caused by the print methods (print.word() and print.cycle()) returning their objects.

I can induce the same error by executing pkgdown::build_reference(). Actually I can delete every Rd file except, say, derangement.Rd and get the same error. I'm pretty sure the problem is in the examples.

one result of this is that the package does not pass R CMD check cleanly on account of the pkgdown site not existing.
