Geometrical Calculations for Multi-Dimensional Box
Calculates the volume, diameter, shortest side, side lengths, or eroded volume of a multi-dimensional box.
## S3 method for class 'boxx' diameter(x) ## S3 method for class 'boxx' volume(x) ## S3 method for class 'boxx' shortside(x) ## S3 method for class 'boxx' sidelengths(x) ## S3 method for class 'boxx' eroded.volumes(x, r)
x |
Multi-dimensional box (object of class |
r |
Numeric value or vector of numeric values for which eroded volumes should be calculated. |
diameter.boxx,
volume.boxx and shortside.boxx
compute the diameter, volume and shortest side length of the box.
sidelengths.boxx returns the lengths of each side of the box.
eroded.volumes.boxx computes, for each entry r[i],
the volume of the smaller box obtained by removing a slab of
thickness r[i] from each face of the box. This smaller box is
the subset consisting of points that lie at least r[i] units
away from the boundary of the box.
For diameter.boxx, shortside.boxx and
volume.boxx, a single numeric value.
For sidelengths.boxx, a numeric vector of length equal to
the number of spatial dimensions.
For eroded.volumes.boxx, a numeric vector of the same length
as r.
