Function to build funnel limits

Description

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

Usage

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

Arguments

min_x	Minimum predicted value for range of x-axis
max_x	Maximum predicted value for range of x-axis
min_y	Minimum ratio value for range of y-axis
max_y	Maximum ratio value for range of y-axis
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.

Value

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