> checking files in 'vignettes' ... NOTE
The following directory looks like a leftover from 'knitr':
'figure'
Please remove from your package.

Error: R CMD check found WARNINGs
Execution halted
Exited with status 1.
Refer to the solution via Leftovers from knitr as showing below but not helps.
One solution is to put
figure$
cache$
in a .Rbuildignore file in the main package directory. This only works if you R CMD check on a built tarball rather than on the package source directory, but that's recommended as best practice anyway ... and it's effectively (I think) what the "Check" button in RStudio does, i.e. calling devtools::check , which automatically builds and checks a source package, using all known best practices.
