################## ### Module 10 Lab # 1/8/2015 ## Download the "Real Property Taxes" Data from my website (via OpenBaltimore): ## http://www.biostat.jhsph.edu/~ajaffe/winterR_2015/data/Real_Property_Taxes.zip ## and unzip it to a .csv file # Read the Property Tax data into R and call it the variable `tax`, and then # subset the data to only retain those houses that are principal residences. # 1. Make boxplots using ggplot2 graphics showing cityTax # by whether the property is a principal residence or not. # 1. Convert the 'lotSize' variable to a numeric square feet variable. # Tips: - Assume hyphens represent decimal places within measurements. # - 1 acre = 43560 square feet # 2. How many values of lot size were missing? # 3. Plot your numeric lotSize versus cityTax on principal residences.
