GetEndo: Get the altered endogenous metabolites from the differential compounds

Description

A function to get the altered endogenous metabolites by similarity analysis on the list of differential compounds and the list of pre-dose compounds.

Usage

GetEndo(pre,A,simidata,sim=80,filepath,design)

Arguments

pre

The pre-dose dataset (data frame).

A

The differential compounds which is derived from the GetDiffData function.

simidata

The same compounds of drug and pre-dose metabolome data, which is derived from Simi.

sim

The parameter (percentage) for similarity analysis. Default: 80.

filepath

A character string indicating the path where the results may be saved in.

design

(optional) a study design dataset(data frame with required format).Use data(design) to see the detailed format. Default:"FALSE"

Value

A data frame which is the list and data of altered endogenous metabolites.

A folder named "EndogenousMetabolites" containing a file named "EndogenousMetabolites.xlsx" will be created automatically which is the list and data of altered endogenous metabolites. And the foreground color of the same compounds produced by Simi will be marked with light blue. If the study design is given by right format, the meal times and sleep times will be marked as yellow and grey.
