Dear R developers,
I am facing an issue while submitting update to my package PGRdup (https://github.com/aravind-j/PGRdup).
With R-devel Debian (2021-02-05 r7994) on submission a WARNING was reported as follows. .
.Quitting from lines 536-542 (Introduction.Rmd) 
Error: processing vignette ‘Introduction.Rmd’ failed with diagnostics:
cannot xtfrm data frames
--- failed re-building ‘Introduction.Rmd’

I am unable to replicate the same locally with the same version (2021-02-05 r79941) in Ubuntu 18.
Is this a false positive ? How to resolve this issue for successful submission.

Best Regards
J. Aravind
