Track snapshot use and remove unused snapshots

[stefanfritsch]

Hi,

I don't think there is a FR for something like this atm. The .checkpoint folder can grow quite large and has to be cleaned up by hand currently (afaik?).

If checkpoint put a simple .lastaccessed file in each snapshot and updated that every time checkpoint was set to the respective snapshot then it would be trivial to write a function that removed all snapshots that are older than a certain date:

remove_not_used(since = "2015-01-01")
remove_not_used(in = ddays(90))

That is also something e.g. RRO could put in .Rprofile.

Thx
Stefan

Very nice suggestion! Thank you.

I have implemented as follows:

checkpointRemove(snapshotDate, checkpointLocation = "~/",
  allSinceSnapshot = FALSE, allUntilSnapshot = FALSE,
  notUsedSince = FALSE, days)

Right now this is only in the dev branch.

@stefanfritsch Can you please test and provide feedback?
