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

[Spencer Graves]

In R Markdown, you can say, "The number `r round(pi)` will appear as 
"The number 3".  If you write "`round`", it should display "round" in a 
special font for R commands.  Meanwhile "$\sigma > 2\Phi^{-1}(q)$" 
passes the string between the two dollar signs to a LaTeX processor.  If 
you already know this, I apologize for wasting your time with this 
reply.  If you did not know this, it might help you understand the 
problem.  Spencer Graves

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?
