rrCC {CC} | R Documentation |

## Individuals Charts Parameters for Baseline RR Mean and Variability

### Description

This function computes control limits for the x-charts for the mean and standard deviation (reciprocal) of R wave to R wave values for heart rate, optionally revising them in the case that individual sample means and/or ranges plot out of the trial control limits.

### Usage

```
rrCC(RR, k=3, revise=TRUE, newdata)
```

### Arguments

`RR` |
a data frame with 2 columns, the first containing rr averages and the second containing rr variances |

`k` |
the control chart parameter governing the width of the control limits |

`revise` |
if TRUE, mu and sigma are estimated using only range values that plot inside the trial control limits |

`newdata` |
a 2 column matrix consisting of data from new subgroups, with averages in the first column and variances in the second column |

### Value

an object of class "CC"
