Draw error shading

Description

A wrapper function for the polygon function to draw error shadings (or confidence intervals) on a line plot.

Usage

Polyplot(x, y1, y2, col = "black", alpha = 0.2, ...)

Arguments

x	numeric vector of x values of the error band.
y1	numeric vector for the upper bound of the error band; must be of the same length as x.
y2	numeric vector for the lower bound of the error band; must be of the same length as x.
col	colour of the error band.
