On this Picostat.com statistics page, you will find information about the bigcity data set which pertains to Population of U.S. Cities. The bigcity data set is found in the boot R package. Try to load the bigcity data set in R by issuing the following command at the console data("bigcity"). This may load the data into a variable called bigcity. If R says the bigcity data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data with library("boot") followed by data("bigcity"). 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 bigcity 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 bigcity R data set. The size of this file is about 334 bytes.
