Last Updated: Mar 11, 2023

Description#

Calculates the centroid locations for the giotto polygons

Usage#

createSpatialFeaturesKNNnetwork(
  gobject,
  method = c("dbscan"),
  feat_type = NULL,
  name = "knn_feats_network",
  k = 4,
  maximum_distance = NULL,
  minimum_k = 0,
  add_feat_ids = FALSE,
  verbose = TRUE,
  return_gobject = TRUE,
  toplevel_params = 2,
  ...
)

Arguments#

gobject

giotto object

method

kNN algorithm method

feat_type

feature type to build feature network

name

name of network

k

number of neighbors

maximum_distance

maximum distance bewteen features

minimum_k

minimum number of neighbors to find

add_feat_ids

add feature id names (default = FALSE, increases object size)

verbose

be verbose

return_gobject

return giotto object (default: TRUE)

toplevel_params

toplevel value to pass when updating giotto params

...

additional parameters to pass to kNN

Value#

If return_gobject = TRUE a giotto object containing the network will be returned. If return_gobject = FALSE the network will be returned as a datatable.
