Draws a rectangle on the current figure filled with arbitrary symbols.

Usage

rectFill(x1,y1,x2,y2,fg=par("fg"),bg=par("bg"),xinc=NA,yinc=NA,
  pch=1,pch.cex=1,pch.col=par("fg"),...)

Arguments

x1,y1,x2,y2: Rectangle limits as in rect.
fg: Foreground color
bg: Background color
xinc,yinc: The x and y increments of spacing for the symbols.
