massvector {mscalib}R Documentation

Constructor

Description

massvector extends matrix

Usage

massvector(info,masses,tcoor)

Arguments

info a unique identifier for the list.
masses a matrix or a array with masses. First column must contain masses.
tcoor a array of length two if integer sample support coordinates.

Details

The class massvector keeps the masses and their intensities in a matrix. It stores additional attributes like the coordinates of the mass spectrometric sample on the support. It also stores a identifier of the massvector.
