  new_max,
  old_min = NULL,
  old_max = NULL,
  na.rm = FALSE
)

Arguments

x

Numeric vector to scale.

new_min

Minimum value of target range.

new_max

Maximum value of target range.

old_min

Minimum value of original range.

If NULL, this is the minimum value in `x`.

old_max

Maximum value of original range.

If NULL, this is the maximum value in `x`.

na.rm
