This is a package for teaching statistical methods in the
        field of Quality Science. It covers distribution fitting,
        process capability, Gage R&R, factorial, fractional factorial
        design as well as response surface methods including the use of
        desirability functions. Define - Pareto Chart; Measure -
        Probability and Quantile-Quantile Plots, Process Capability
        Ratios for various distributions and Gage RR Analyze i.e.
        Pareto Chart, Multi-Vari Chart, Dot Plot; Improve - Full and
        fractional factorial, response surface and mixture designs as
        well as the desirability approach for simultaneous optimization
        of more than one response variable. Normal, Pareto and Lenth
        Plot of effects as well as Interaction Plots; Control - Quality
        Control Charts can be found in the qcc package. The focus is on
        teaching the statistical methodology used in the Quality
        Sciences.

<ul><li>26. Feb 2011: Updated the vignette to explain the usage and scope of
    the cg method.
    Updated the vignette to untangle the R-Code used into a file called RCode.R.
    All examples are now easily reproducible.</li><li>11 Feb 2011: gageRRDesign now support nested designs. gageRR can be
    called with method = "nested".
    number of distinctive categories (i.e. ndc) is being calculated within the
    gageRR method</li><li>10 Feb 2011: plot method for objects of class gageDesign now includes
    the plotting of Range and Average charts.</li><li>18 Jan 2011: included the gage capability method cg to calculate and
    visualize the cg and cgk index</li><li>10 Dec 2010: gageRR with no interaction term is now calculated
    correctly. Bug in gageRR was found by user.</li></ul>
