Scales each curve to the range \([0, 1]\) (or custom range).
This preserves the shape while normalizing the range.
Usage
scale_minmax(fdataobj, min = 0, max = 1)
# S3 method for class 'fdata'
scale_minmax(fdataobj, min = 0, max = 1)
# S3 method for class 'irregFdata'
scale_minmax(fdataobj, min = 0, max = 1)
Arguments
- fdataobj
An object of class 'fdata'.
- min
Target minimum value (default 0).
- max
Target maximum value (default 1).
Value
A scaled 'fdata' object where each curve is in the specified range.
Examples
fd <- fdata(matrix(rnorm(100) * 10 + 50, 10, 10), argvals = seq(0, 1, length.out = 10))
fd_scaled <- scale_minmax(fd)
# Check: each curve now in [0, 1]
apply(fd_scaled$data, 1, range)
#> [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
#> [1,] 0 0 0 0 0 0 0 0 0 0
#> [2,] 1 1 1 1 1 1 1 1 1 1
