Thierry very gently (yet correctly) suggested to have the "cached" results as
"precomputed" artifacts in the package to not require any compution at all.
So write, for example, a data.frame df as
     saveRDS(df, "inst/cachedData/data.rds")
and then in your vignette retrieve it as
     df <- readRDS(system.file("cachedData", "data.rds", package="mypkg"))
replacing "mypkg" with your package name.

Cheers, Dirk
