On this R-data statistics page, you will find information about the Gunnels data set which pertains to Gunnels. The Gunnels data set is found in the Stat2Data R package. You can load the Gunnels data set in R by issuing the following command at the console data("Gunnels"). This will load the data into a variable called Gunnels. If R says the Gunnels data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") 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 Gunnels R data set. The size of this file is about 39,986 bytes.

Water	Standing water in the quadrat? 1=yes or 2=no
Cobble	Rocky cobbles? 1=yes or 2=no

Details

This datset comes from a study on the habitat preferences of a species of eel, called a gunnel. Biologist Jake Shorty sampled quadrats along a coastline and recorded whether or not the species was found in the quadrat.
