square {matRiks}

Coordinates of a square

Description

Define the coordinates for drawing a square

Usage

square(
  size.x = 15,
  size.y = size.x,
  rot = pi/4,
  pos.x = 0,
  pos.y = 0,
  shd = NA,
  vis = 1,
  lty = 1,
  lwd = 3
)

square4(
  size.x = sqrt(square()$size.x[[1]]^2/2),
  size.y = size.x,
  pos.x = size.x,
  pos.y = size.x,
  lwd = 3,
  lty = 1
)

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 size.x.

rot

define the rotation. Default is \frac{pi}{4}

pos.x

numeric, position on the x axis. Default is 0.

pos.y

numeric, position the y axis, Default is 0.

shd

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

vis

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

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.

Value

Return the coordinates for drawing a square

Return the coordinates for drawing a square composed of 4 lines

Functions

• square4(): Coordinates of a square composed of 4 lines

  Define the coordinates for drawing a square composed of 4 lines

Examples

# return the default coordinates for drawing a square
square()
# change the coordinates for drawing a smaller square
square(size.x = 5)
# default coordinates of square composed of 4 lines
square4()
# draw square composed of 4 lines with different lty
draw(square4(lty = 2))
