rescale_11 rescales every vector in a list of vectors to the range [-1, 1]. rescale_11 rescales the vectors as a group (instead of rescaling each vector independently). This is a helpful feature for rescaling related variables (such as xmin and xmax) without nullifying the difference between the two.
1 | rescale_11(xvars, xlim = NULL, zero = FALSE)
|
xvars |
a list of vectors |
xlim |
NULL (default) or a numeric vector of length two that specifies the range of values to scale to [-1, 1] |
zero |
logical. Should zero be added to the range before rescaling? |
If a vector is a character or factor vector, rescale_11 attempts to coerce it to numeric before scaling. The scale is determined by finding the range of values contained in the list of vectors and mapping it ot [-1, 1].
If the full range of values to be scaled is not present in the vectors, users can specify the range to be scaled to [-1,1] with the xlim argument. Values in the vectors will be rescaled as if they according to this range.
