Usage

wall(xlim = c(0, 1), ylim = c(0, 1), xpd = TRUE, ...)

Arguments

xlim

Numeric vector of length 2 giving the x coordinate range. Default xlim = c(0, 1).

ylim

Numeric vector of length 2 giving the y coordinate range. Default ylim = c(0, 1).

xpd

Logical value to indicate if all plotting is clipped to the figure region. The default is c(1, 1, 1, 1).

# NOT RUN {
 # latent variables
 attack = latent("ATTACK", x=0.35, y=0.7, rx=0.08, ry=0.06)
 defense = latent("DEFENSE", x=0.35, y=0.3, rx=0.08, ry=0.06)
 success = latent("SUCCESS", x=0.65, y=0.5, rx=0.08, ry=0.06)

 # open diagram
 wall()

 # draw latent variables
 draw(attack)
 draw(defense)
 draw(success)

 # add arrows
 arrow(from=attack, to=success, start="east", end="west")
 arrow(from=defense, to=success, start="east", end="west")
