Plot the distribution of a variable with a center region shaded

Plot the distribution of a variable with a center region shaded. Annotate with the area of the shaded region.

ShadedDensityCenter(
  frame,
  xvar,
  boundaries,
  title,
  ...,
  linecolor = "darkgray",
  shading = "darkblue",
  annotate_area = TRUE
)

Arguments

frame	data frame to get values from
xvar	name of the variable to be density plotted
boundaries	vector of the min and max boundaries of the shaded region
title	title to place on plot
...	no unnamed argument, added to force named binding of later arguments.
linecolor	color of density curve
shading	color of shaded region and boundaries
annotate_area	if TRUE (default), report the area of the shaded region
