In tidymass/massdataset: massdataset

Extract Components from mass_dataset Object

Description

This function extracts the components from an object of class "mass_dataset". It first checks if the object belongs to the class "mass_dataset" and then extracts the expression data.

Usage

extract_expression_data(object)

extract_sample_info(object)

extract_variable_info(object, with_expression_data = FALSE)

extract_annotation_table(object, with_expression_data = FALSE)

extract_variable_info_note(object)

extract_sample_info_note(object)

extract_process_info(object)

extract_ms2_data(object)

Arguments

object	An object of class "mass_dataset" from which the MS2 data will be extracted.
with_expression_data	Logical, whether to include expression data in the output. Default is FALSE.

Value

A data frame containing the expression data or other componets in mass_dataset class.
