transform_log: Transforms the intensities by calculating their log

In metamorphr: Tidy and Streamlined Metabolomics Data Workflows

Transforms the intensities by calculating their log

Description

Log-transforms intensities. The default (base = 10) calculates the log10. This transformation can help reduce heteroscedasticity. See references for more information.

Usage

transform_log(data, base = 10)

Arguments

data	A tidy tibble created by read_featuretable.
base	Which base should be used for the log-transformation. The default (10) means that log10 values of the intensities are calculated.

Value

A tibble with log-transformed intensities.
