Dataset Help

On this Picostat.com statistics page, you will find information about the cfseal data set which pertains to Cape Fur Seal Data. The cfseal data set is found in the DAAG R package. You can load the cfseal data set in R by issuing the following command at the console data("cfseal"). This will load the data into a variable called cfseal. If R says the cfseal 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. 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 cfseal R data set. The size of this file is about 1,566 bytes.
