On this R-data statistics page, you will find information about the geyser data set which pertains to Old Faithful Geyser Data. The geyser data set is found in the MASS R package. You can load the geyser data set in R by issuing the following command at the console data("geyser"). This will load the data into a variable called geyser. If R says the geyser data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data with the library() command.
