04.08.2011: fixed expected fraction nonconforming calculation (ppm) in method pcr corrected the calculation of standard deviation based on subgroups
27. Jul 2011: in vignette, corrected typo in formula for c_pu i.e. capability for process capability regarding upper specification limit
14. Jul 2011: included the calculation of lambda for a boxcox transformation in function pcr. Only specified specification limits are plotted. fraction nonconforming are calculated in percentages and ppm
13. Jul 2011: reference line for Quantil-Quantil and Probability Plots changed Anderson Darling test now reports the name of the dataset passed from method pcr Reference line of QQ-Plot within method pcr changed
12. Jul 2011: reference line for normalPlot changed Included color coding of sigfnifican effects
11. Jul 2011: added parameters xlim, ylim and border for qqPlot Added parameter border for ppPlot
21. Mar 2011: added missing documentation for S4 classes. Included a visually more appealing DMAIC cycle in the vignette
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.
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
10 Feb 2011: plot method for objects of class gageDesign now includes the plotting of Range and Average charts.
18 Jan 2011: included the gage capability method cg to calculate and visualize the cg and cgk index
10 Dec 2010: gageRR with no interaction term is now calculated correctly. Bug in gageRR was found by user.
