[R] [R-pkgs] New package: epidata

Hey folks, epidata — https://cran.r-project.org/package=epidata — hit CRAN a few days ago. It provides tools to retrieve Economic Policy Institute data library extracts from their "hidden"-but-well-conceived API, returning pristine data frames. EPI provides researchers, medi
