tsMSdata-class: Class for representing MS data

Description

This is a class to represent MS data obtained from the sample.

Objects from the Class

Objects be created by calls of the form

Slots

RI:

"list", a list containing an RI matrix, one matrix per metabolite

RT:

"list", a list containing an RT matrix, one matrix per metabolite

Intensity:

"list", a list containing a peak intensity matrix, one matrix per metabolite

Methods

Intensity

signature(obj = "tsMSdata"): gets the peak intensity list.

Intensity<-

signature(obj = "tsMSdata"): gets the peak intensity list.

retIndex

signature(obj = "tsMSdata"): gets RT list.

retIndex<-

signature(obj = "tsMSdata"): sets the RI list.

retTime

signature(obj = "tsMSdata"): gets the RT list.

retTime<-

signature(obj = "tsMSdata"): sets the RT list.

show

signature(object = "tsMSdata"): show function.

as.list

signature(object = "tsMSdata"): coerce a list object. See details

Details

The method as.list converts every slot (RI, RT, and Intensity) of a tsMSdata object into a matrix. The converted matrices are stored in a list. Each converted matrix has an attribute called 'index' that relates the metabolite index with the respective rows. The components of the resulting list are named as the slots. If the slot RT is not defined or empty, then the output list will have only two components. ('RT' and 'Intensity').
