filledcircle {shape} | R Documentation |
plots (part of) outer and inner circle and colors inbetween; color can be a palette
filledcircle(r1=1, r2=0, mid=c(0,0), dr=0.01, from=-pi, to=pi, col=femmecol(100), values=NULL, zlim=NULL, lwd=2, lcol=NA, ...)
r1 |
radius of outer circle |
r2 |
radius of inner circle |
mid |
midpoint of circle |
dr |
size of segments, in radians, to draw circle (decrease for smoother) |
from |
starting angle for circle segment, radians |
to |
final angle for circle 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" |
