Hello,
Here is a PR to refactor the functions in getData.R and getData_nodocker.R. My primary motivation was to support data.table's fread() csv import function to speed up CSV imports for large files. While I was doing that I tried to refactor the code to remove duplication and add roxygen for the man pages. Happy to modify if any changes are preferred.
Here is some testing code that I tried on BIDMC data (7.2 million rows):
Cheers,
Chris
