To be sure, you'd need to ask the CRAN staff, but probably not. You could probably add an option that defaults to FALSE to persist the data. Then wrap that in a check. if persist=TRUE, check to see if the file exists. if it exists in the subdirectory of the working directory, then load it. otherwise create the subdirectory of the current working directory, load from the internet, and save the data locally. In this way you've had the user explicitly direct the function to save data to disk, which is (usually) OK. Regards, Brian -- Brian G.
