transform_power: Transforms the intensities by calculating their _n_th root

In metamorphr: Tidy and Streamlined Metabolomics Data Workflows

Transforms the intensities by calculating their nth root

Description

Calculates the nth root of intensities with x^(1/n). The default (n = 2) calculates the square root. This transformation can help reduce heteroscedasticity. See references for more information.

Usage

transform_power(data, n = 2)

Arguments

data	A tidy tibble created by read_featuretable.
n	The nth root to calculate.

Value

A tibble with power-transformed intensities.
