shadowbox: adds a box with a shadow to a plot

In diagram: Functions for Visualising Simple Graphs (Networks), Plotting Flow Diagrams

Description

adds a box, with shadow on a plot; used for writing text

Usage

shadowbox(box.type = "rect", mid, radx, rady = radx, 
          shadow.size = 0.01, shadow.col = "grey",
          box.col = "white", lcol = "black", lwd = 1,  
          dr = 0.01, angle = 0, len = 1, nr = 5, rx = rady,
          theta = 90, ...)

Arguments

box.type	shape of the box.
mid	midpoint (x,y) of the box.
radx	horizontal radius of the box.
rady	vertical radius of the box.
shadow.size	relative size of shadow.
shadow.col	color of shadow.
box.col	fill color of the box.
lcol	line color surrounding box.
lwd	line width of line surrounding the box.
dr	if box is curved: size of segments, in radians, to draw ellipse (decrease for smoother).
angle	rotation angle, degrees.
len	if box.type="cylinder": length of the cylinder.
nr	if box.type="multi": the number of angles.
rx	if box.type="round", the radius of the rounded part.
theta	if box.type="parallel", angle of the bottom, left corner of the parallelogram, in degrees.
...	other arguments.

Details

one box is drawn, centered aroung point mid and with horizontal and vertical radiusses radx, rady.

By default, a shadow is drawn, in the right-lower corner of the box.

The shadow color and relative size is specified with shadow.col and shadow.size respectively.

shadow.size = 0 toggles off the drawing of the shadow.

the type of the box is set with box.type which can take on the values:

• "rect": a rectangle.

• "ellipse": an ellipse.

• "diamond": a diamond.

• "round": a rectangle with rounded sides.

• "hexa": a hexagonal shape.

• "multi": a multigonal shape; also input "nr", the number of angles.

• "cylinder": a cylindrical shape; also input "len", the length of the cylinder.

• "parallel": a parallelogram; “theta” is the angle of the bottom left corner.

the fill-color of the box is specified with box.col;

the line width and color of the box are specified with lwd and lcol

Examples

openplotmat(main="shadowbox")

shadowbox(box.type = "rect", mid = c(0.1, 0.5),
          rady = 0.1, radx = 0.05, angle = 25)

shadowbox(box.type = "round", mid = c(0.3, 0.5),
          rady = 0.05, radx = 0.025, angle = 90,
          shadow.col = "darkred")

shadowbox(box.type = "ellipse", mid = c(0.5, 0.5),
          rady = 0.05, radx = 0.075, box.col = "blue")
          
shadowbox(box.type = "multi", mid = c(0.8, 0.5),
          rady = 0.05, radx = 0.05, box.col = "darkblue", nr = 5)
