On this R-data statistics page, you will find information about the synth.tr data set which pertains to Synthetic Classification Problem. The synth.tr data set is found in the MASS R package. You can load the synth.tr data set in R by issuing the following command at the console data("synth.tr"). This will load the data into a variable called synth.tr. If R says the synth.tr 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 synth.tr R data set. The size of this file is about 6,097 bytes.
