scale_vast_grouped: Scale intensities of features using grouped vast scaling

In metamorphr: Tidy and Streamlined Metabolomics Data Workflows

Scale intensities of features using grouped vast scaling

Description

A variation of scale_vast but uses a group-specific coefficient of variation and therefore requires group information. See scale_vast and the References section for more information.

Usage

scale_vast_grouped(data, group_column = .data$Group)

Arguments

data	A tidy tibble created by read_featuretable.
group_column	Which column should be used for grouping? Usually grouping_column = Group. Uses args_data_masking.

Value

A tibble with vast scaled intensities.
