color palette to be used; also allowed are two extremes or
one value.
values
if not NULL, a matrix providing (radius,z-values)
couples, used for coloring.
zlim
Only if values is not NULL: the minimum and maximum z values
for which colors should be plotted, defaulting to the range of the
finite values of the second column of values.
lwd
width of external line.
lcol
line color.
angle
angle of rotation, in degrees.
...
arguments passed to R-function polygon.
Details
If angle=0, coloration starts from top to bottom. This is different
from filledmultigonal,
where coloration proceeds from middle to external
wx,wy: horizontal and vertical width of the shape
Here "horizontal" and "vertical" denote the position BEFORE rotation
values: if not NULL, a matrix providing (radius,z-values)
couples, used for coloring.
Here radius are positive values denoting the relative distance between
the shapes centre and edge.
The radiusses are rescaled to be in [0,1] if needed.
z-values (2nd column of values) together with zlim and
col denote the coloration level.
Colors in col will be interpolated to the z-values and used to
color an interval as given by the input radiusses.
