Applied Data Visualization with R and ggplot2

Activity: Using Faceting to Understand Data

Steps for Completion:

1. Use the loan data and plot a histogram (use fill color=cadetblue4 and bins=10).
2. Use facet_wrap() to plot the loan data for the different credit grades.
3. Now, you will need to change the default options for facet_wrap, in order to produce the following plots. Use ?facet_wrap on the command line to view the options that can be changed.

Outcome:

Refer to the complete code at the following path: https://goo.gl/RheL2G. The answers to the questions are given here:

1. scale=free_y.
2. A, B, and C have maximum loan amounts below 10,000. (A, B, C, and D is also an acceptable answer.)
3. F and G show uniform distributions.
4. No, none of the distributions are normally distributed.
