Rescale numbers

Description

Rescales numbers from one scale to another. By default, assumes that the old scale has min and max values represented in the vector, but this can be overwritten.

Usage

rescale(
  x,
  new_min,
  new_max,
  old_min = min(x, na.rm = T),
  old_max = max(x, na.rm = T)
)

Arguments

x	(num vectr) A vector of values.
new_min	(num sclr) The new scale minimum.
new_max	(num sclr) The new scale maximum.
old_min	(num sclr) The old scale minimum. Default: min(x).
old_max	(num sclr) The old scale maximum. Default: max(x).

Examples

rescale(1:10, new_min = 0, new_max = 1) #converts to 0, ..., 1
rescale(1:10, new_min = 0, new_max = 5) #converts to 0, ..., 5
rescale(rnorm(10), new_min = 1, new_max = 100) %>% sort #converts to 1, ..., 1
rescale(c(.1, .5, 1), new_min = 10, new_max = 20, old_min = 0, old_max = 1) #assume old numbers belong to scale 0-1, rescale to 10-20 scale, i.e. 11, 15, 20
