[Bioc-devel] saving and obtaining a list with BiocFileCache package

Hello Arman,

I would be possible to save the list as an Rdata object.  The process would be

  1.  create a new item in the cache and retrieve the path
  2.  use that path in a save( listObj,  file="path")

Then you could load the RData object in your next session and it would be available for use.

Something along the following would save:

myList = list()

bfc = BiocFileCache()

path = bfcnew(bfc, "someIdentifiers key words or name of your list", ext="RData)

save(myList, file=path)

For retrieval in next session:

# get the rid of the list

bfcquery(bfc, c("someIdentifiers key words")

# then choose what rid you want to load from the cache and use that to retrieve path - in this case BFC12:

path = bfcpath(bfc, "BFC12")

Hi, it is possible to save a list with BiocFileCache package and then obtain the same list from it? I have read the vignette but I couldn’t figure it out. It looked like that I have saved the list to hard drive, but I’m not sure whether it is still a list or can be obtained as a list. If it is possible to do so, I would be grateful if someone would kindly provide the code, if not, I appreciate recommending an alternative package.

Best regards,
