[R-pkg-devel] check cross-references error: Non-file package-anchored link(s)

[Zhian Kamvar]

Hello,

I noticed a strange error pop up for R-devel (2020-06-12 r78687) check on travis: https://travis-ci.org/github/grunwaldlab/poppr/jobs/697831376#L4653-L4654

* checking Rd cross-references ... WARNING
Non-file package-anchored link(s) in documentation object 'aboot.Rd':
  ‘[ape:phylo]{ape::phylo()}’

I looked at the Cross-reference section of WRE, but I couldn't find any mention of non-file package-anchored links being a problem: https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Cross_002dreferences

Is this a new policy?

All the best,
Zhian
