I have one data set that I ship as a few principal components and
reconstruct it by a function. The result is then assigned to the
exported variable by delayedAssign.
That way, you'd need to ship the raw data only, but can provide a
ready-to-use R object as well.
For my example data, I don't ship the raw data as it is too big (30 MB
toy example is really unpolite on CRAN), but I provide it at r-forge and
give the link on the help page and in the vignette.
