[R] Package build help - thanks

[Glenn Schultz]

Hello All,

I have finally addressed all the cmd issues with my package build "bondlab."  I would like to thank everyone that took the time to answer my questions.  I have the following question:  Currently the package has a non-standard directory/folder structure.  The non-standard folders are listed below.  I use connections to open and close directories during an analysis run.  I don't think having these directories in the bondlab directory is a long term viable option as the number of mortgage and REMIC cusips is well over 2 million.  My question is two parts:

First part, what do you believe is the best way to store these objects as blobs (everything is serialized) in a database or in a folder structure residing on the local machine.
In the event I first start with a folder structure on a local machine.  Is it possible to instruct R to create the directory and move the examples to the appropriate folder?  For example, could I create a folder data and then move each of the below folders to data and on install move the "data folders" to say a bondlabdata folder?
Best Regards,
Glenn
