On this Picostat.com statistics page, you will find information about the votes.repub data set which pertains to Votes for Republican Candidate in Presidential Elections. The votes.repub data set is found in the cluster R package. Try to load the votes.repub data set in R by issuing the following command at the console data("votes.repub"). This may load the data into a variable called votes.repub. If R says the votes.repub data set is not found, you can try installing the package by issuing this command install.packages("cluster") and then attempt to reload the data with library("cluster") followed by data("votes.repub"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing votes.repub at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the votes.repub R data set. The size of this file is about 9,009 bytes.
