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

[Jose Barrera]

Dear Dirk,

Thanks for clarifying, now I can see Thierry's point. But the issue is that
doing that my vignette would lose the "reproducible research" property
because the Rnw would need all those artefacts to reproduce the pdf. I know
I could combine Thierry's suggestion with playing with echo = TRUE/FALSE,
eval = TRUE/FALSE and purl = TRUE/FALSE in the chunks so that the pdf (and
the purled R file) looks like I don't save/retrieve partial results but I
would like to find a more elegant solution in which the Rnw reproduces the
pdf from scratch while taking advantage of "cache = TRUE" present in some
chunks, as we can do locally.

Best,


Jose Barrera
