[R-pkg-devel] proper way to cite an invalid URL

[Jason Cory Brunson]

Hello,

I'm trying to submit a new version of a package to CRAN. Among the 
additions is an RMarkdown vignette that uses data from a website that is 
no longer active. For completeness, i'd still like to cite the invalid 
URL, but without formatting it as a hyperlink. What is the preferred way 
to do this?

One StackExchange answer is to surround the URL with <span></span>, but 
this did not remove the hyperlink when i rendered the vignette locally. 
Instead, i surrounded it with back-ticks, which works locally, but i've 
been unable to run Win-Builder checks to see whether this prevents the 
"invalid URLs" NOTE. And, even if the NOTE is prevented, i'm not sure 
this is preferred.

Thank you,

Cory Brunson
