On this Picostat.com statistics page, you will find information about the crabs data set which pertains to Morphological Measurements on Leptograpsus Crabs. The crabs data set is found in the MASS R package. You can load the crabs data set in R by issuing the following command at the console data("crabs"). This will load the data into a variable called crabs. If R says the crabs 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. 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 crabs R data set. The size of this file is about 6,927 bytes.
