# The purpose of this script is to demonstrate how the e_data, f_data, and
# e_meta data frames were created. It should NOT be rerun because the data sets
# in pmartRdata will change over time and this will lead to errors in the unit
# tests.
# Fabricate the data to test the as.metabData function. ------------------------
# I am saving these data sets (even though they are exact copies) in case the
# data sets in the pmartRdata package change in the future. If they do, the
# tests will not need to be updated to reflect changes in the new data.
# Load necessary libraries.
