draw.arc {plotrix} | R Documentation |
Draw one or more arcs using classic graphics.
draw.arc(x=1,y=NULL,radius=1,angle1=deg1*pi/180,angle2=deg2*pi/180, deg1=0,deg2=45,n=35,col=1,...)
x |
x coordinate of center. Scalar or vector. |
y |
y coordinate of center. Scalar or vector. |
radius |
radius. Scalar or vector. |
angle1 |
Starting angle in radians. Scalar or vector. |
angle2 |
Ending angle in radians. Scalar or vector. |
deg1 |
Starting angle in degrees. Scalar or vector. |
deg2 |
Ending angle in degrees. Scalar or vector. |
n |
Number of polygons to use to approximate the arc. |
col |
Arc colors. |
... |
Other arguments passed to segments. Vectorization is not supported for these. |
Draws one or more arcs from angle1 to angle2. If angle1 is numerically greater than angle2, then the angles are swapped.
Returns a matrix of expanded arguments invisibly.
