Dear Rusers, I want to standardise the values of x/y coordinates to the unit
square, i.e. make the x-values all lie within [0,1] and all the y-values lie
within [0,1] in the bottom example. I had thought to use scale() function to
do it, but it seems that it's used to standardise a variable and the scaled
value was not within [0,1]. OR, i can divide x/y-values by their maximum value
to get it. I'm not sure about it.#Example data data <- matrix(1:10, nc=2)
data<-as.data.frame(data)
names(data)<-c('x','y')> data
x y
1 1 6
2 2 7
3 3 8
4 4 9
5 5 10 I'd appreciate your help.
