Paste your R script for each koan into the text box. This grader checks what you wrote between the koan markers (like #1@ and #@1). It does not execute R.
Paste your Koan 8 script. You must include the marker blocks for #1@, #2@, and #3@.
Paste your Koan 9 script. You must include blocks for #1@ through #@5.
Paste your Koan 10 script. You must include blocks #01@ to #@19. This grader is flexible about the alternatives you listed (binwidth, alpha values, color vs fill, and some scale options).
