R problems for practice

Practice problem 1

  • Produce a histogram of the humidity recordings in the weather data frame with a bin width of 15 and white border color.

  • Use ?geom_histogram to determine how to remove all missing values from the histogram and then do that.

  • Complete PS5 by 10 AM on Wednesday

Plans for next time

  • Plicker questions over Sections 4.1 - 4.4
  • More review of plotting in R with practice problems
  • Time to ask questions about Lab 2
