Description

adds a rectangular box with rounded left and right edges to a plot

Usage

roundrect(mid, radx, rady, rx=rady, dr=0.01, 
  col="white", lcol="black", lwd=2, angle=0, ...)

Arguments

mid midpoint (x,y) of the box.
radx horizontal radius of the box.
rady vertical radius of the box.
rx radius of rounded part.
dr size of segments, in radians, to draw the rounded line (decrease for smoother).
col fill color of the box.
lcol line color surrounding box.
lwd line width of line surrounding the box.
angle rotation angle, degrees.
