vol.sph | R Documentation |
Calculates the (volume) size of the spherical volume segment defined by 'r', 'theta' and 'phi'.
vol.sph(
r = c(0, 1),
theta = c(0, 2 * pi),
phi = c(0, pi),
var = c("volx", "harx")
)
r |
is range of radial coordinates, given as a vector of interval values (in which case length(r)-1 spherical segemnts are treated) or as a two column matrix where the first column represents the lower limit of the sperical segments, and the second column represents the upper limit. |
theta |
is the range of azimuth angles in radians, given in the same way as 'r'. |
phi |
is the range of elevation angles in radians, given in the same way as 'r. |
var |
is a vector of the variables to return. Currently implemented are "volx" for volumes of the voxels and "harx" for horizontal area of the voxels. |
