• rendering issues. Not sure why,, attaching my knit which seems to work when removing line breaks around first $$
  lab05_multiple_regression.html
• suggest re-naming x-axis "length centered" in second ggplot. Suggest to re-orient y-axis to 0.
• the moth data is loaded twice, with multiple library calls for FANR6750
• moth data variables load correctly, and don't need re-assigning for factor.
• suggest R chunks should have title
• suggest add "Assignment 3" title
