ISAtab-class: Class '"ISATab"', a class for maintaing ISATab information

In Risa: Converting experimental metadata from ISA-tab into Bioconductor data structures

Description

This class maintains information from an ISATab dataset, including an investigation file, one or more study files, and one or more assay files for each study file.

Objects from the Class

Objects can be created by calls of the form new("ISATab", ...).
