workflow for exporting raw / derived data objects

[egouldo]

#10 partially solved, knock-on problem:

See Hadley's notes here
http://r-pkgs.had.co.nz/data.html

Why I want to share CSV files of each of the RDA files:

• want language agnostic data files
• want them to be viewable within the repository... Github renders files nicely in your browser

Why this isn't great

• when data is automatically loaded from the data/ folder, CSV files arent properly imported... each value is squished into a single character string across all variables
• aside from this, storing files as CSVs loses information about the variable types upon import... feather would be cool here. rda will do because I don't know how to change the method for loading data files inside data/ within packages... I think it uses the data() function... would be nice to override this with something else...
