On this Picostat.com statistics page, you will find information about the roller data set which pertains to Lawn Roller Data. The roller data set is found in the DAAG R package. Try to load the roller data set in R by issuing the following command at the console data("roller"). This may load the data into a variable called roller. If R says the roller data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data with library("DAAG") followed by data("roller"). 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 roller 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 roller R data set. The size of this file is about 89 bytes.
