In lava: Latent Variable Models

Add Confidence limits bar to plot

Description

Add Confidence limits bar to plot

Usage

confband(
  x,
  lower,
  upper,
  center = NULL,
  line = TRUE,
  delta = 0.07,
  centermark = 0.03,
  pch,
  blank = TRUE,
  vert = TRUE,
  polygon = FALSE,
  step = FALSE,
  ...
)

Arguments

x	Position (x-coordinate if vert=TRUE, y-coordinate otherwise)
lower	Lower limit (if NULL no limits is added, and only the center is drawn (if not NULL))
upper	Upper limit
center	Center point
line	If FALSE do not add line between upper and lower bound
delta	Length of limit bars
centermark	Length of center bar
pch	Center symbol (if missing a line is drawn)
blank	If TRUE a white ball is plotted before the center is added to the plot
vert	If TRUE a vertical bar is plotted. Otherwise a horizontal bar is used
polygon	If TRUE polygons are added between 'lower' and 'upper'.
step	Type of polygon (step-function or piecewise linear)
...	Additional low level arguments (e.g. col, lwd, lty,...)
