Rchartsd
(Package: SSDforR) :
SPC R-chart using standard deviation
The R-Chart is designed to detect changes in variation over time. This is one of two forms of the R-chart and should be used with samples larger than ten. This function uses the standard deviation of samples to track variation.

CDCabove
(Package: SSDforR) :
Conservative Dual Criteria (CDC) desired zone above lines
The conservative dual-criteria (CDC) is a relatively new approach to comparing phases that works well when data have a moderate lag-1 autocorrelation (lower than 0.6). This function uses two lines to define the desired zone: the mean and the regression line of the comparison phase.

ABrobust
(Package: SSDforR) :
Robust regression
