g.sphere {ReacTran} | R Documentation |
Surface Area and Volume of Geometrical Objects
Description
g.sphere
the surface and volume of a sphere
g.spheroid
the surface and volume of a spheroid
g.cylinder
the surface and volume of a cylinder;
note that the surface area calculation ignores the top and bottom.
Usage
g.sphere(x)
g.spheroid (x, b=1)
g.cylinder (x, L=1)
Arguments
x |
the radius
|
b |
the ratio of long/short radius of the spheroid;
if b<1: the spheroid is oblate.
|
L |
the length of the cylinder
|
Value
A list containing:
surf |
the surface area
|
vol |
the volume
|
