Create base funnel plot elements

Creates the common elements for a funnel plot including theme, scales, reference line, control limits, and caption. Used as a foundation for provider-specific funnel plots.

Usage

funnelbase(
  xname,
  yname,
  xlim,
  ylim,
  caption,
  legend.position,
  legend.position.inside,
  calc_cl
)

Arguments

xname

Character, x-axis label

yname

Character, y-axis label

xlim

Numeric vector of length 2, x-axis limits

ylim

Numeric vector of length 2, y-axis limits

caption

Character, plot caption

legend.position

Character or numeric vector, legend position

legend.position.inside

Numeric vector of length 2, position for internal legend

calc_cl

Function that calculates control limits

Value

List of ggplot2 elements

Examples

if (FALSE) { # \dontrun{
library(ggplot2)

# Simple example
p <- ggplot(data = data.frame(x = 1:10, y = 1:10)) +
  funnelbase(
    xname = "Sample Size",
    yname = "Rate",
    xlim = c(0, 10),
    ylim = c(0, 10),
    caption = "Example funnel plot",
    legend.position = "top",
    legend.position.inside = c(0.85, 0.1),
    calc_cl = function(x, p) p * x # Example control limit function
  )} # }
