On this Picostat.com statistics page, you will find information about the car90 data set which pertains to Automobile Data from 'Consumer Reports' 1990. The car90 data set is found in the rpart R package. Try to load the car90 data set in R by issuing the following command at the console data("car90"). This may load the data into a variable called car90. If R says the car90 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 with library("rpart") followed by data("car90"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing car90 at the command-line which should display the entire dataset. 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 car90 R data set. The size of this file is about 20,391 bytes.
