RESCALE: Rescale a variable (e.g., from 5-point to 7-point).

Description

Rescale a variable (e.g., from 5-point to 7-point).

Usage

RESCALE(var, from = range(var, na.rm = T), to)

Value

A vector of rescaled variable.

Arguments

var

Variable (numeric).

from

Numeric vector, the range of old scale (e.g., 1:5). If not defined, it will compute the range of var.

to

Numeric vector, the range of new scale (e.g., 1:7).

Examples

d = data.table(var=rep(1:5, 2))
added(d, {
  var1 = RESCALE(var, to=1:7)
  var2 = RESCALE(var, from=1:5, to=1:7)
})
d  # var1 is equal to var2
