...
)Arguments
- x
point pattern
- nvec
which jumps to consider
- r_adjust
consider only fry points with length r_adjust*max(window side)
- nangles
If 3d, number of refinements (def=2), in 2d def=20 sectors.
- eps
add to the sector angle. Results in smoothing if >0 (default=0).
- cylindric
Use a cylinder instead of a sector
- double
Should we use both directions of a pair
- border
Should border effects be cancelled by minus sampling, if TRUE, "double" ignored.
- origin
Constrain the ellipses' centers to origo.
- keep_data
Keep the data for each ellipsoid, inside each ellipsoids? Helps with averaging.
- data
The vectors to which fit ellipses. Default is missing, and we compute Fry-points.
- ALS
(false) Use ALS to refine OLS fits.
