This question is related to the filehash package only.
I would like to use the filehash package because of it's ability to deal
with large amounts of data. I've set up a filehash database on a network
drive and populated it with several GB of data. Somehow, I must have
corrupted the files because I cannot access the objects anymore. Here is
what I do:
> require(filehash)
> filehashOption(defaultType = "RDS") # need this, dbInit will fail
> db <- dbInit("//nas-msw-07/app/Prices/Historical")
> hPP <- db2env(db) # put all the data in an enviroment
> ("commod xyz ex" %in% ls(hPP))
[1] TRUE
> dbExists(db, "commod xyz ex")
[1] TRUE
> dbFetch(db, "commod xyz ex")
Error in unserialize(con) : error reading from connection
> hPP[["commod xyz ex"]]
Error in unserialize(con) : error reading from connection
>
How do I get to touch the data again? It's really slow to recreate the
filehash again, and it seems to be very fragile. Any suggestions much
appreciated.
Thank you,
Adrian Dragulescu
