Background of a Plot

Paints the background of the plot, using either the figure region, the plot region or both. It can sometimes be cumbersome to elaborate the coordinates and base R does not provide a simple function for that.

Usage

setBackCol(col = "grey", region = c("plot", "figure"), border = NA)

Arguments

col

the color of the background, if two colors are provided, the first is used for the plot region and the second for the figure region.

region

either "plot" or "figure"

border

color for rectangle border(s). Default is NA for no borders.

Value

No return value (invisible NULL), called for its side effect of painting the background of the current plot.

Examples

# use two different colors for the figure region and the plot region
plot(x = rnorm(100), col="blue", cex=1.2, pch=16,
     panel.first={setBackCol(c("red", "lightyellow"))
                  grid()})
