The CSV file, CO-EST2012-Alldata.csv, is provided on the book's website in its original form. The following expression reads its contents and assigns it to a data.frame object named dat:

> dat = read.csv("C:\\Data\\CO-EST2012-Alldata.csv")

The expression colnames(dat) reveals that we have as many as 52 variables in this table. To save space, only the first 15 values are printed here:

> colnames(dat)[1:15] [1] "SUMLEV" "REGION" "DIVISION" [4] "STATE" "COUNTY" "STNAME" [7] "CTYNAME" "CENSUS2010POP" "ESTIMATESBASE2010" [10] "POPESTIMATE2010" "POPESTIMATE2011" "POPESTIMATE2012" [13] "NPOPCHG_2010" "NPOPCHG_2011" "NPOPCHG_2012"
