```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,
