[R-pkg-devel] Rmarkdown vignette yields r inline warning on windows build

[Matthew Young]

I am trying to submit a package to CRAN that includes a vignette built using rmarkdown.  It passes fine on the machines I have access to (ubuntu and osx).  When I submit to CRAN using the form, it passes the Debian checks, but fails on windows with the following WARNING:

! Missing $ inserted.
<inserted text>
                $
l.1030

You may need to add $ $ around a certain inline R expression `r `


I’m really not sure what is causing this error or how to debug it.  I do not have any inline r expressions in my vignette (code here https://github.com/constantAmateur/SoupX/blob/devel/vignettes/pbmcTutorial.Rmd).  I do have back-ticked expression such as `round`, but they are not executed code.  Can anyone suggest what might be causing this issue?

Many thanks,

Matthew
