Here's the data link: 
simon <- read.csv(url("http://goo.gl/exQA14"))

Here's the link to the codebook: 
http://opensiuc.lib.siu.edu/cgi/viewcontent.cgi?article=1010&context=ppi_statepolls

Install these pacakges: 
install.packages("dplyr")
install.packages("car")

Load these packages: 
library(dplyr)
library(car)

Here are some sample codes:
simon$downstate <- Recode(simon$area, "3=1; else=0")

black <- filter(simon, rac_eth == 2)

hist(simon$area)

Do the following exercises. 
1. Create a new dichotomous variable that is a measurement of males. Do the same for females. 

2. There's a question in the dataset asking about term limits. Clean that up so that higher values are favor and lower values are oppose. 
You have to deal with that "don't know" response, as well. 

3. Use filter to create a dataset of just females. And create a dataset of just males. 

4. Compare how males and females feel about term limits.
