On this R-data statistics page, you will find information about the agefat data set which pertains to Total Body Composision Data . The agefat data set is found in the HSAUR R package. You can load the agefat data set in R by issuing the following command at the console data("agefat"). This will load the data into a variable called agefat. If R says the agefat data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") 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 agefat R data set. The size of this file is about 415 bytes.
