CoreSet-class: A Superclass to Contain Data for Genetic Profiling and...

In CoreGx: Classes and Functions to Serve as the Basis for Other 'Gx' Packages

Description

The CoreSet (CSet) class was developed as a superclass for objects in the PharmacoGx and RadioGx packages to contain the data generated in screens of cancer cell lines for their genetic profile and sensitivities to therapy (Pharmacological or Radiation). This class is meant to be a superclass which is contained within the PharmacoSet (PSet) and RadioSet (RSet) objects exported by PharmacoGx and RadioGx. The format of the data is similar for both data PSets and RSets, allowing much of the code to be abstracted into the CoreSet super-class. However, the models involved with quantifying cellular response to Pharmacological and Radiation therapy are widely different, and two seperate implementations of the CSet class allows the packages to apply the correct model for the given data.
