filledellipse {shape} | R Documentation |
plots (part of) outer and inner ellipses and colors inbetween; color can be a palette
filledellipse(rx1=1, rx2=0, ry1=rx1, ry2=NULL, mid=c(0,0), dr=0.01, angle=0, from=-pi, to=pi, col=femmecol(100), values=NULL, zlim=NULL, lwd=2, lcol=NA, ...)
rx1 |
horizontal radius of outer ellipse |
rx2 |
horizontal radius of inner ellipse |
ry1 |
vertical radius of outer ellipse |
ry2 |
vertical radius of inner ellipse |
mid |
midpoint of ellipse |
dr |
size of segments, in radians, to draw ellipse (decrease for smoother) |
angle |
rotation angle, degrees |
from |
starting angle for ellipse segment, radians |
to |
final angle for ellipse segment, radians |
col |
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 |
... |
arguments passed to R-function "polygon" |
draws (part of) an outer and inner ellipse, as specified by inner and outer radiusses: rx1,ry1: horizontal and vertical radiusses of outer ellipse; rx2,ry2: same for inner ellipse. Here "horizontal" and "vertical" denote the position BEFORE rotation
Fills with a palette of colors inbetween
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.
If rl2, the long radius of the inner ellipse is 0, the ellipse is full
