Dataset Help

On this Picostat.com statistics page, you will find information about the condroz data set which pertains to Condroz Data . The condroz data set is found in the robustbase R package. You can load the condroz data set in R by issuing the following command at the console data("condroz"). This will load the data into a variable called condroz. If R says the condroz data set is not found, you can try installing the package by issuing this command install.packages("robustbase") 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 condroz R data set. The size of this file is about 3,394 bytes.
