R Dataset / Package MASS / cpus

Documentation

On this Picostat.com statistics page, you will find information about the cpus data set which pertains to Performance of Computer CPUs. The cpus data set is found in the MASS R package. You can load the cpus data set in R by issuing the following command at the console data("cpus"). This will load the data into a variable called cpus. If R says the cpus 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 cpus R data set. The size of this file is about 9,216 bytes.
