You can load the xclara data set in R by issuing the following command at the console data("xclara"). This will load the data into a variable called xclara. If R says the xclara data set is not found, you can try installing the package by issuing this command install.packages("cluster") 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 xclara R data set. The size of this file is about 54,501 bytes.
