addbg: Add an opaque background to a plot when plotting

In geneorama/geneorama: Gene's collection of miscellaneous functions

Description

Adds a transparent foreground and gridlines to plots to create the illusion of a background.

Usage

addbg(
  color = heat.colors(40, alpha = 0.15)[30],
  linecolor = "grey75",
  addgridlines = TRUE
)

Arguments

color	Background color. The default is a yellow from ' heat.colors that happens to look reasonable when alpha is applied.
linecolor	Color used for gridlines. Default is "grey75"
addgridlines	Add gridlines? Default is TRUE

Details

The background and gridlines can be slightly more professional looking and easier to read. The color can be customized, the default is heat.colors(40, alpha=.15)[30].

This is something that's nice if you're too pressed for time to do it using ggplot.

Uses the info in par("usr") to draw a rectangle that is the same size as your current plot area. Sometimes the transparency doesn't show up well when copied into other applications, so use at your own risk.
