Classes

Class	Description
CChart	`CChart` is a c-chart for monitoring the count of the number of defects when defects are rare. Control limits are computed using the Poisson distribution. If defects are not rare NpChart should be used instead.
ControlLimit	`ControlLimit` is a control limit line on a process control chart.
CuSum	`CuSum` is a cumulative sum chart. It is more efficient than a Shewhart chart for detecting small shifts in the mean of a process.
CuSumStatus	`CuSumStatus` is a cumulative sum status chart. CuSumStatus plots the tabular CuSum results.
EWMA	`EWMA` is an exponentially weighted moving average control chart.
NpChart	`NpChart` is an np-chart for monitoring the number of defects when defects are not rare.
ParetoChart	`ParetoChart` is a Pareto bar chart.
PChart	`PChart` is a p-chart for monitoring the defect rate when defects are not rare.
RChart	`RChart` is an R chart using sample ranges to monitor the variability of a process. Each sample must contain at least two observations. The range of a sample is the maximum observed value minus the minimum observed value.
SChart	`SChart` is an S chart using sample standard deviations to monitor the variability of a process. This is normally used with sample sizes greater than 10.
ShewhartControlChart	`ShewhartControlChart` is the base class for the Shewhart control charts.
UChart	`UChart` is a u-chart for monitoring the defect rate when defects are rare.
XbarR	`XbarR` is an X-bar chart for monitoring a process using sample ranges.
XbarS	`XbarS` is an X-bar chart for monitoring a process using sample standard deviations.
XmR	`XmR` is an XmR chart for monitoring a process using moving ranges.
