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