The primary source for these data is the Cook Political Report web site. However, the current URL we have for these data on that web site includes "2012" in the title. If and when the numbers are updated, we would expect that file name to change.
To avoid that problem the code is currently set to read from the Wikipedia article on "Cook Partisan Voting Index".
The algorithm reads the web site into a list,
finds the desired tables on the list, then parses
and formats them as desired. Then it merges the
results with UShouse and USsenate.
A list with components "House" and "Senate".
Each contains a data.frame. The
"House" data.frame returned by readCookPVI
includes the following columns:
State |
name of the state |
District |
District, e.g, |
PVInum |
PVI as a number ranging from roughly 50 to 150. 100 means that the vote split in that district was within 0.5 percent of the national average. 101 means that it tilts 1 percent (after rounding) to Republican. 98 means that it tilts 1 percent to Democratic; 99 is not used. |
PVIchar |
PVI rating in character format. For example, 'D+1' means that the vote tilted 1 percent toward Democratic more than the national average. 'R+1' means that it tilted 1 percent toward Republican. |

The 'Senate' data.frame includes the following columns:

House balance as a number with 0 = 100 percent Democratic, 99.9 = 100 percent Republican, and 500 for the same number of Republicans as Democrats. |
houseBalanceChar |
