meps_r_pkg's Introduction

meps_r_pkg

meps_r_pkg is an R library designed to facilitate loading and manipulation of public use files (PUFs) from the Medical Expenditure Panel Survey Household Component (MEPS-HC):

get_puf_names() returns a current list of the names of MEPS public use files.
read_MEPS() loads MEPS public use files (PUFs) directly from the MEPS website. Internet connection required.
dl_meps() downloads MEPS public use files (PUFs) from the MEPS website and saves to local directory. Internet connection required.
