filledmultigonal {shape}R Documentation

adds a colored and rotated multigonal shape to a plot

Description

draws and colors a rotated shape with equal-sized vertices ; color can be a palette.

Usage

filledmultigonal(mid=c(0,0), rx=1, ry=rx, nr=4, 
  col=femmecol(100),values=NULL, zlim=NULL,lwd=2,lcol=NA,angle=0, ...)

Arguments

mid midpoint of multigonal.
rx horizontal radius.
ry vertical radius.
nr number of sides.
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.

Details

Coloration proceeds from midpoint to external edge

rx,ry: horizontal and vertical radiusses 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.
