[R] How to make our data normally distributed in R

[Rui Barradas]

Hello,

To rescale data so that their values are between 0 and 1, use this function:


scale01 <- function(x, na.rm = FALSE){
   (x - min(x, na.rm = na.rm))/(max(x, na.rm = na.rm) - min(x, na.rm = 
na.rm))
}

x <- c(SVM=3500,
        ANN=4600,
        R.Forest=2900)

scale01(x)
#      SVM       ANN  R.Forest
#0.3529412 1.0000000 0.0000000


See base R function ?scale for another way of scaling data.

As for the second question, if your RMSE vector had values in the range 
2900 to 4600 and the y axis limits are c(0, 1), how can you expect to 
see anything?

Hope this helps,

Rui Barradas
