Calculates the centroid locations for the polygons within one selected layer
Usage
addSpatialCentroidLocationsLayer(
gobject,
poly_info = "cell",
feat_type = NULL,
provenance = poly_info,
spat_loc_name = "raw",
return_gobject = TRUE
)
Arguments
- gobject
giotto object
- poly_info
polygon information
- feat_type
feature type
- provenance
(optional) provenance to assign to generated spatLocsObj. If not provided, provenance will default to
poly_info
- spat_loc_name
name to give to the created spatial locations
- return_gobject
return giotto object (default: TRUE)
Value
If return_gobject = TRUE
the giotto object containing the
calculated polygon centroids will be returned.
If return_gobject = FALSE
only the generated polygon centroids
will be returned as spatLocsObj.
