backGround: Background and grid color control.

In prodlim: Product-Limit Estimation for Censored Event History Analysis

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.
