filledrectangle {shape} | R Documentation |
plots and colors a rotated rectangle; color can be a palette
filledrectangle(mid=c(0,0), wx=1, wy=wx, col=femmecol(100), values=NULL, zlim=NULL, lwd=2, lcol=NA, angle=0, ...)
mid |
midpoint of rectangle. |
wx |
horizontal width. |
wy |
vertical width. |
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. |
angle |
angle of rotation, in degrees. |
... |
arguments passed to R-function polygon. |
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.
