Value

The coordinates for drawing an upward-facing left semi-circle

The coordinates a upward-facing left semi-circle

Arguments

size.x

numeric, define the semi-major axis of the ellipse within which the figure is inscribed. Default is sqrt(square()$ size.x[[1]]^2 /2)

size.y

numeric, define the semi-minor axis of the ellipse within which the figure is inscribed. Default is 0

pos.x

numeric, position on the x axis. Default is 0

pos.y

numeric, position the y axis, Default is 0

theta1

Starting angle of the circle section. Default is 3*pi/4.

theta2

Ending angle of the circle section (built counterclockwise). Default is 7*pi/4.

shd

character, define the shading of the figure. Default is NA which results in a transparent figure

lty

integer, define the line type of the figure, default is 1 (solid line)

lwd

integer, define the line width of the figure. Default is 3

vis

Visibility of the figure. Default is 1, making the figure visible. To hide the figure, change it to 0
