Yes, you would need to do that.


The solution of adding
\usepackage{url}

and changing to
\url{https://www.bankofcanada.ca/2006/03/working-paper-2006-3}.

does seem to work. (No "on CRAN" confirmation yet but I have not had the
immediate pre-test rejection that I got previously.)


The risk of this change is that the URL may fail in CRAN tests; see the 
recent "URL checks" thread on R-devel for a discussion of ways in which 
this can happen even when the URL works for you.

* checking re-building of vignette outputs ... OK
* checking PDF version of manual ... OK
* checking for non-standard things in the check directory ... OK

so I am not sure if it uses texi2dvi. (I haven't used
dvi myself for a long time.)

I'm not sure how to debug this when I can't reproduce
the error. Suggestions would be appreciated.

Re: [R-pkg-devel] CRAN check texi2dvi failure

[Georgi Boshnakov]

The problem is not in the Warning from the example but from the \verb commands 
in the references.
You use space to delimit the argument of \verb and I was surprised that it 
worked since TeX ignores spaces after commands. 
Apparently, this has been an exception for \verb but now this feature is 
considered a bug and hs been recently fixed, see the atacjexchange question 
below and the relevant paragraph from LaTeX News. Probably the linux machines 
have updated their TeX installations.

In short, changing the space tp  say  +  delimiter for \verb command should fix 
the issue.

https://tex.stackexchange.com/questions/566085/how-does-verb-detect-spaces-that-shouldnt-exist
 

Avoid problematic spaces after \verb
If a user typed \verb␣!~!␣foo instead of \verb!~!␣foo
by mistake, then surprisingly the result was “!~!foo”
without any warning or error. What happened was that
the ␣ became the argument delimiter due to the rather
complex processing done by \verb to render verbatim.
This has been fixed and spaces directly following the
command \verb or \verb* are now ignored as elsewhere.

I am trying to debug a problem that is appearing in the linux and Solaris

https://cran.r-project.org/web/checks/check_results_tsfa.html

The problem is with re-building the vignette
   ...

  Error(s) in re-building vignettes:

   ...

In responding to the threat of removal I have also fixes some long standing 
warnings about adding imports to the NAMESPACE. The new version builds with 
--as-cran giving no errors or warnings with both R-devel on win-builder

so I am not sure if it uses texi2dvi. (I haven't used dvi myself for a long
