Challenge Overview

Today’s challenge is to:

  1. read in a data set, and describe the data set using both words and any supporting information (e.g., tables, etc)
  2. tidy data (as needed, including sanity checks)
  3. identify variables that need to be mutated
  4. mutate variables and sanity check all mutations

Read in data

Read in one (or more) of the following datasets, using the correct R package and command.

  • abc_poll.csv ⭐
  • poultry_tidy.csv⭐⭐
  • FedFundsRate.csv⭐⭐⭐
  • hotel_bookings.csv⭐⭐⭐⭐
  • debt_in_trillions ⭐⭐⭐⭐⭐
Code
ABC <- read.csv("_data/abc_poll_2021.csv")
view(ABC)

Briefly describe the data

Tidy Data (as needed)

Is your data already tidy, or is there work to be done? Be sure to anticipate your end result to provide a sanity check, and document your work here.

Any additional comments?

Identify variables that need to be mutated

Are there any variables that require mutation to be usable in your analysis stream? For example, are all time variables correctly coded as dates? Are all string variables reduced and cleaned to sensible categories? Do you need to turn any variables into factors and reorder for ease of graphics and visualization?

Document your work here.
