R is freely available under the GNU General Public License, and can be loaded as a module on Viper (with Linux), Windows (PC) and Mac.
Programming example
x <- c(151, 174, 138, 186, 128, 136, 179, 163, 152, 131) y <- c(63, 81, 56, 91, 47, 57, 76, 72, 62, 48) # Apply the lm() function. relation <- lm(y~x) print(relation)
Modules Available
