Dataset Help
On this Picostat.com statistics page, you will find information about the cu.summary data set which pertains to Automobile Data from 'Consumer Reports' 1990. The cu.summary data set is found in the rpart R package. You can load the cu.summary data set in R by issuing the following command at the console data("cu.summary"). This will load the data into a variable called cu.summary. If R says the cu.summary data set is not found, you can try installing the package by issuing this command install.packages("rpart") 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 cu.summary R data set. The size of this file is about 6,046 bytes.
