added example R script for installing from previous CRAN states with swi... #6

Closed gmbecker closed 9 years ago

gmbecker commented 9 years ago

Example using switchr and crandb to installf rom previous CRAN states.

Wasn't sure where to put the file so I put it in the root directory. Can be moved as desired.

@cboettig Only weeks later than I promised it!

API (name of the Install function) subject to change.

Nice Gabe.

Using this system "one" could easily setup and populate legacy MRAN snapshots repositories (which started something like july 2014)

P.s By the way I do not think that the head and tail params are actually used in DB().

@kforner, I wondered about the tail thing too. That isn't my code (if it were it wouldn't be using the pipe), I lifted directly from the crandb readme.

As for MRAN, yes, we could populate MRAN repositories this way (and the CRAN Archive servers would probably thank us for it), but we also explicitly don't need to. We don't need a (pre-existing) repository at all, just the manifest.

Hi Gabe, sorry for the delay. My use case if a bit different, my starting point is not a manifest, but a list of package names retrieved from dependencies of a set of packages (our own packages, as a matter of fact). So I do not have the versions of the packages, but just a (snapshot) date.

@kforner but crandb is able to map a date to a set of package versions, or more generally to an R version.
