scale_range {transx}

Rescale

Description

Usage

scale_range(x, to, na.rm = getOption("transx.na.rm"))

scale_minmax(x, na.rm = getOption("transx.na.rm"))

scale_unit_len(x, na.rm = getOption("transx.na.rm"))

Arguments

x

⁠[univariate vector]⁠

Univariate vector, numeric or ts object with only one dimension.

to

⁠[numeric(2): NULL]⁠

Values that will determine the output range.

na.rm

⁠[logical(1): getOption("transx.na.rm")]⁠

A value indicating whether NA values should be stripped before the computation proceeds.

Details

To rescale a range between an arbitrary set of values [a, b], the formula becomes:

Value

Returns a vector with the same class and attributes as the input vector.

Examples

x <- c(10,5,1,-2)
scale_range(x, c(-1, 2))
scale_minmax(x)
