adds a colored and rotated rectangle to a plot
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 |
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 |
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.
