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
Bg(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.
# use two different colors for the figure region and the plot regionplot(x = rnorm(100), col="blue", cex=1.2, pch=16,
