[R-pkg-devel] Cache in vignette not working when checking a package

[Jose Barrera]

Dear Thierry,

Thanks for your advice. However, I would like to understand why when I
build the vignette to get the pdf from the Rnw, it takes just 8 seconds
once the "cache" folder has been created instead of the initial 4 minutes,
but this time reduction does not happen when checking the package.

Best,

Jose Barrera
