backGround

Background and grid color control.

Description

Some users like background colors, and it may be helpful to have grid lines to read off e.g. probabilities from a Kaplan-Meier graph. Both things can be controlled with this function. However, it mainly serves plot.prodlim.

Usage

backGround(xlim, ylim, bg = "white", fg = "gray77",
  horizontal = NULL, vertical = NULL, border = "black")

Arguments

`xlim`	Limits for the xaxis, defaults to par("usr")[1:2].
`ylim`	Limits for the yaxis, defaults to par("usr")[3:4].
`bg`	Background color. Can be multiple colors which are then switched at each horizontal line.
`fg`	Grid line color.
`horizontal`	Numerical values at which horizontal grid lines are plotted.
`vertical`	Numerical values at which vertical grid lines are plotted.
`border`	The color of the border around the background.
