The traditional approach to lab reports

Excel and Word

  • Enter values into Excel
  • Try to get chart/plot to look the way you want
  • Copy figure into Word document
  • Identify key values from your analysis
  • Provide comments on trends in the plot
  • "Print off" and turn in

What if you need to make modifications?

  • Try to follow how you created formulas in Excel for analysis
  • Make sure to not inadvertently change any Excel cell values
  • Redo making of Excel figure(s) (often from scratch)
  • Remember to copy new figure(s) into Word document
  • Remember to update values in modified Word document
  • This process is often tedious and frustrating.

    What if there was a better way?

Use R!

What is R?

  • R is a completely free software package and language for statistical analysis and graphics.
  • It excels in helping you with
    • data manipulation
    • automation
    • reproducibility
    • improved accuracy
    • error finding
    • customizability
  • Any downsides?

Learning how to use R

RStudio, R Markdown, & me!

  • RStudio is a powerful user interface that helps you get better control of your analysis.
  • It is also completely free.
  • You can write your entire paper/report (text, code, analysis, graphics, etc.) all in R Markdown.
  • If you need to update any of your code, R Markdown will automatically update your plots and output of your analysis and will create an updated PDF file.
  • No more copy-and-paste!
  • My main responsibility in this position is to help members of the Reed community learn R and help them with their analysis and graphics.
