Hi "e",
Here is a simple function to use the attributes from one scaled object
to scale another.
x = data.frame(a=1:10,b=11:20)
y = data.frame(a=2:11,b=12:21)
s <- scale(x)
## function to scale x using attributes from trained
scale2 <- function(x, trained) {
x <- as.matrix(x)
x <- sweep(x,

I would like to scale a data frame and then using the same scaling
parameters scale on another data frame. This will be helpful in scaling the
test dataset based on train dataset's scaling parameters. I couldn't find
any utility functions that do this. Any suggestions on how to approa
