1. Watch the Introduction to Repeating Things in R video:

2. Watch the Using Vectorized Functions video:

3. Do Size Estimates Vectorized.

Note: The next two videos use the base R apply functions. We now use the equivalent map functions from the purrr package: map_dbl() instead of sapply() and map2_dbl() instead of mapply(). The ideas are the same, but the map functions take the vector(s) first and the function last. See the lecture notes for examples.

4. Watch the Apply Functions video:

5. Do Size Estimates with Maximum.

6. Watch the Using mapply For Functions with Multiple Vector Arguments video:

7. Do Task 1 in Size Estimates By Name Apply.

8. Watch the Combining Your Own Functions With dplyr video:

9. Do Task 2 in Size Estimates By Name Apply.

10. Finish the Repeating Things 1 assignment
