Your Turn 1: Consider
What do you do when you want to learn a new package?
Your Turn 2
Open vignettes/intro-to-avalanchr.Rmd.
Let’s add some more content before we knit this vignette. Lines 2729 have an R Markdown code chunk. On line 28, fill in the blank with this code: db_con(“residents_per_sector”)
Let’s also add some examples of the summarizing and plotting functions. On line 57, fill in the blank with count_donations(). On line 62, use plot_donations()
Knit the vignette. If you’re having trouble finding some of your functions, try re-loading or documenting and re-building.
