In metamorphr: Tidy and Streamlined Metabolomics Data Workflows

Normalize intensities across samples using a normalization factor

Description

Normalization is done by dividing the intensity by a sample-specific factor (e.g., weight, protein or DNA content). This function requires a sample-specific factor, usually supplied via the Factor column from the sample metadata. See the Examples section for details.

Usage

normalize_factor(data, factor_column = .data$Factor)

Arguments

data	A tidy tibble created by read_featuretable.
factor_column	Which column contains the sample-specific factor? Usually factor_column = Factor. Uses args_data_masking.

Value

A tibble with intensities normalized across samples.

Examples

toy_metaboscape %>%
  join_metadata(toy_metaboscape_metadata) %>%
  normalize_factor()
