On this Picostat.com statistics page, you will find information about the mammals data set which pertains to Brain and Body Weights for 62 Species of Land Mammals. The mammals data set is found in the MASS R package. You can load the mammals data set in R by issuing the following command at the console data("mammals"). This will load the data into a variable called mammals. If R says the mammals 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 mammals R data set. The size of this file is about 1,272 bytes.
