In this exercise, you'll use both iotools and bigtabulate to tabulate borrower race and ethnicity by year.

Instructions

iotools and bigtabulate are loaded in your workspace.

  • Create a function make_table() that reads in chunk as a matrix and then tabulates it by borrower race and year.
  • Use chunk.apply() to import the data from the file connection we created for you.
  • Convert race_year_table to a data frame.
