Add an AB line to your graph

You need specify only one of x, or y, or x1,x2,y1,y2

agg_abline(x = NULL, y = NULL, x1 = NULL, y1 = NULL, x2 = NULL,
  y2 = NULL, colour = "black", panel, lwd = 1, lty = 1, color)

Arguments

x

Draw a vertical line at x (omit to draw a specific AB line)
y

Draw a horizontal at y omit to draw a specific AB line)
x1

For specific AB lines: the first x coordinate
y1

For specific AB lines: the first y coordinate
x2

For specific AB lines: the second x coordinate
y2

For specific AB lines: the second y coordinate
colour

The colour of the AB line (default black)
panel

Which panel should the line be placed on? You can specify a vector of panels (e.g. `panel = c("1","3")`) to apply the line to multiple panels at once.
lwd

(Optional, default 1) The linewidth
lty

(Optional, default 1) The line type
color

(Deprecated; use colour instead) The colour of the AB line (default black)
