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

Annual Precipitation in US Cities


The average amount of precipitation (rainfall) in inches for each of 70 United States (and Puerto Rico) cities.




A named vector of length 70.


The dataset version up to Nov.16, 2016 had a typo in "Cincinnati"'s name. The examples show how to recreate that version.
