createSpatialDelaunayNetwork

Create a spatial Delaunay network based on cell centroid physical distances.

createSpatialDelaunayNetwork(
  gobject,
  method = c("deldir", "delaunayn_geometry", "RTriangle"),
  dimensions = "all",
  name = "Delaunay_network",
  maximum_distance = "auto",
  minimum_k = 0,
  options = "Pp",
  Y = TRUE,
  j = TRUE,
  S = 0,
  verbose = T,
  return_gobject = TRUE,
  ...
)

Arguments

gobject

giotto object

method

package to use to create a Delaunay network

dimensions

which spatial dimensions to use. Use "sdimx" (spatial dimension x), "sdimy", "sdimz" respectively to refer to X (or the 1st), Y (or the 2nd) and Z(or the 3rd) dimension, see details. (default = all)

name

name for spatial network (default = 'delaunay_network')

maximum_distance

distance cuttof for Delaunay neighbors to consider. If "auto", "upper wisker" value of the distance vector between neighbors is used; see the boxplotgraphics documentation for more details.(default = "auto")

minimum_k

minimum number of neigbhours if maximum_distance != NULL

options

(geometry) String containing extra control options for the underlying Qhull command; see the Qhull documentation (../doc/qhull/html/qdelaun.html) for the available options. (default = 'Pp', do not report precision problems)

Y

(RTriangle) If TRUE prohibits the insertion of Steiner points on the mesh boundary.

j

(RTriangle) If TRUE jettisons vertices that are not part of the final triangulation from the output.

S

(RTriangle) Specifies the maximum number of added Steiner points.

verbose

verbose

return_gobject

boolean: return giotto object (default = TRUE)

...

Other additional parameters

Value

giotto object with updated spatial network slot

Details

Creates a spatial Delaunay network as explained in delaunayn (default), deldir, or triangulate.
