Unsure of NOTES from rhub::check_for_cran()

,

I ran rhub::check_for_cran() on my R package, conrad, hoping to do one last check before submitting to CRAN. I see these notes and was wondering what these mean:

Here is the full log: https://builder.r-hub.io/status/conrad_1.0.0.tar.gz-b00b0e7f1e0b45f48178c18e15d8ea98

I was unable to find NULL or lastMiKTeXException in my files/directories.

Probably an R-hub issue, so ignore it
