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

[Uwe Ligges]

My wild guess is that 'r ' indicates there is an invisible char after 
the r that is not representable in the chosen encoding.

Best,
Uwe Ligges

I do not have any inline r expressions in my vignette (code here https://github.com/constantAmateur/SoupX/blob/devel/vignettes/pbmcTutorial.Rmd [github.com]<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_constantAmateur_SoupX_blob_devel_vignettes_pbmcTutorial.Rmd&d=DwMF-g&c=D7ByGjS34AllFgecYw0iC6Zq7qlm8uclZFI0SqQnqBo&r=XXcY8t_J1mVMCDTmi3629g&m=KD5hkiMRJXvOAV1srKNufKVz3MOekQAmaDIOmgmxB6A&s=1GWJLKyp3TJoM0X6-KWdkBEwtTer6JTOQKvF0d5iSPE&e=>).  I do have back-ticked expression such as `round`, but they are not executed code.  Can anyone suggest what might be causing this issue?
