textellipse: adds lines of text in an ellipsoid box to a plot

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

Description

adds one or more lines of text, centered around "mid" in an ellipsoid box

Usage

textellipse(mid, radx, rady = radx*length(lab), lwd = 1,  
            shadow.size = 0.01, adj = c(0.5, 0.5), lab = "", 
            box.col = "white", lcol = "black", shadow.col = "grey", 
            angle = 0, dr = 0.01, ...)

Arguments

mid	midpoint (x,y) of the box.
radx	horizontal radius of the box.
rady	vertical radius of the box.
lwd	line width of line surrounding the box.
shadow.size	relative size of shadow.
adj	text adjustment.
lab	one label or a vector string of labels to be added in box.
box.col	fill color of the box.
lcol	line color surrounding box.
shadow.col	color of shadow.
angle	rotation angle, degrees.
dr	size of segments, in radians, to draw ellipse (decrease for smoother).
...	other arguments passed to function textplain.
