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.
