• Review important steps for making sure your code runs everywhere
• Important for class - your code has to run the on graders computer
• Important for science
  • next day (who has gotten code working & had it not work the next day?)
  • desktop vs. laptop
  • collaborators
  • advisor

Make sure things you did before don't matter

• Change something

• Looks like it still works

• Only works because of something you did earlier in the same session

• Clear R environment using the broom icon on the Environment tab.

• Run entire file using Source button or Ctrl-Shift-Enter

Make sure code works on other computers

• Don't use setwd()
• Use projects and relative paths
  • data/mydata.csv not C:\Users\Batman\DataCarp\data\mydata.csv
• Filenames in code should match actual names exactly, including capitalization
