Plot the distribution of a variable with a tail shaded

Source: R/ShadedDensity.R

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

ShadedDensity(
  frame,
  xvar,
  threshold,
  title,
  ...,
  tail = "left",
  linecolor = "darkgray",
  shading = "darkblue",
  annotate_area = TRUE
)

Arguments

frame

data frame to get values from
xvar

name of the variable to be density plotted
threshold

boundary value for the tail
title

title to place on plot
...

no unnamed argument, added to force named binding of later arguments.
tail

which tail to shade, 'left' (default) or 'right'
linecolor

color of density curve
shading

color of shaded region and boundaries
annotate_area

if TRUE (default), report the area of the shaded region
