x0, y0, angle, arr.length, arr.width,
lcol, lty and arr.col can be a vector,
of the same length.
if arr.adj = 0.5, then the centre of the arrowhead is
at the point at which it is drawn.
arr.adj = 1 causes the tip of the arrowhead to
touch the point.
arr.adj = 0 causes the base of the arrowhead to
touch the point.
The type of the arrowhead is set with arr.type which can take
the values:
"triangle": uses filled triangle
"curved" : draws arrowhead with curved edges
"circle" : draws circular head (where arr.width=arr.length)
"ellipse" : draws ellipsoid head

x0, y0, x1, y1, arr.length,
arr.width, arr.adj, lcol, lty and
arr.col can be a vector, of the same length.
For each 'i', an arrow is drawn between the point '(x0[i], y0[i])' and the point '(x1[i],y1[i])'.
If code=1 an arrowhead is drawn at '(x0[i],y0[i])'
if code=2 an arrowhead is drawn at '(x1[i],y1[i])'.
If code=3 an arrowhead is drawn at both ends of the arrow
unless arr.length = 0, when no head is drawn.
If arr.adj = 0.5 then the centre of the arrowhead is at
the point at which it is drawn.
arr.adj = 1 causes the tip of the arrowhead to touch
the point.
arr.adj = 2 causes the base of the arrowhead to touch
the point.
The type of the arrowhead is set with arr.type which can take
the values:
"simple" : uses comparable R function arrows
"triangle": uses filled triangle
"curved" : draws arrowhead with curved edges
"circle" : draws circular head
"ellipse" : draws ellepsoid head
"T" : draws T-shaped (blunt) head

rx and ry are the horizontal and vertical radiusses of the
ellipses.
The ellipse is drawn from the point defined by from to the point defined
as to which are joined anti-clockwise.
if arrow is TRUE, an arrow is drawn along the path of the
ellipse.
arr.length and arr.width set the size of the arrow.
The type of the arrowhead is set with arr.type which can take
the values:
"simple" : uses comparable R function arrows.
"triangle": uses filled triangle.
"curved" : draws arrowhead with curved edges.
"circle" : draws circular head.
arr.pos, a real value between 0 and 1 gives the position
(0=start,1=end).
arr.col specifies the color, arr.code specifies where the
angle points to.
arr.adj specifies the position adjustment - see Arrows
for details.
