##  To do before running this script in RStudio:
#   1) copy txt from git-hub working directory to a folder in your R working directory
#             titled "txt_2022_3_28".
#     Note 1: Text comes from 2022-3-28. All changes to the corpus made
#                 after this date are excluded from analysis.
#     Note 2: Workflow follows format presented by Julia Silge and David Robinson: Tidy Text
#       https://cran.r-project.org/web/packages/tidytext/vignettes/tidytext.html
