Description Usage Arguments Details Value See Also

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)

`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]

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.

a list of vectors
