draw.sector {circlize}

Draw sectors or rings in a circle

Description

Draw sectors or rings in a circle

Usage

draw.sector(
    start.degree = 0,
    end.degree = 360,
    rou1 = 1,
    rou2 = NULL,
    center = c(0, 0),
    clock.wise = TRUE,
    col = NA,
    border = "black",
    lwd = par("lwd"),
    lty = par("lty"))

Arguments

start.degree

start degree for the sector

end.degree

end degree for the sector

rou1

Radius for one of the arc in the sector

rou2

Radius for the other arc in the sector

center

Center of the circle

clock.wise

The direction from start.degree to end.degree

col

Filled color

border

Border color

lwd

Line width

lty

Line style

Details

If the interval between start and end (larger or equal to 360 or smaller or equal to -360) it would draw a full circle or ring. If rou2 is set, it would draw part of a ring.
