build_limits_lookup | R Documentation |

Internal function for funnel plot to build the control limits prior to plotting.

```
build_limits_lookup(
min_x,
max_x,
min_y,
max_y,
draw_adjusted,
tau2,
data_type,
sr_method,
target,
multiplier,
denominators
)
```

`draw_adjusted` |
TRUE/FALSE Use overdispersion adjustment |

`tau2` |
If using draw_adjusted, what is the tau2 ("between" standard error) to use? |

`data_type` |
SR, PR or RC. Used to set target reference |

`sr_method` |
Which adjustment method is being used, SHMI or CQC? |

`target` |
target to be used to set centre line |

`multiplier` |
Multiply ratio value by an amount. Default is 1, but some mortality ratios use 100, for example. |

`min_preds` |
Minimum predicted value for range of x-axis |

`max_preds` |
Maximum predicted value for range of x-axis |

`min_ratio` |
Minimum ratio value for range of y-axis |

`max_ratio` |
Maximum ratio value for range of y-axis |

`draw_unadjusted` |
TRUE/FALSE Draw Poisson distribution limits? |

A data.frame with an index column and various control limits based on the index as an x-axis value.
