ctPoly: Plots uncertainty bands with shading

Description

Plots uncertainty bands with shading

Usage

ctPoly(x, y, ylow, yhigh, steps = 20, ...)

Value

Nothing. Adds a polygon to existing plot.

Arguments

x

x values

y

y values

ylow

lower limits of y

yhigh

upper limits of y

steps

number of polygons to overlay - higher integers lead to smoother changes in transparency between y and yhigh / ylow.

...

arguments to pass to polygon()

Examples

plot(0:100,sqrt(0:100),type='l')
ctPoly(x=0:100, y=sqrt(0:100), 
yhigh=sqrt(0:100) - runif(101), 
ylow=sqrt(0:100) + runif(101),
col=adjustcolor('red',alpha.f=.1))
