Last Updated: Jan 29, 2024

Description#

Function to get a dimension reduction object

Usage#

get_dimReduction(
  gobject,
  spat_unit = NULL,
  feat_type = NULL,
  reduction = c("cells", "feats"),
  reduction_method = c("pca", "umap", "tsne"),
  name = "pca",
  output = c("dimObj", "data.table"),
  set_defaults = TRUE
)

Arguments#

gobject

giotto object

spat_unit

spatial unit (e.g. “cell”)

feat_type

feature type (e.g. “rna”, “dna”, “protein”)

reduction

reduction on cells or features (e.g. “cells”, “feats”)

reduction_method

reduction method (e.g. “pca”, “umap”, “tsne”)

name

name of reduction results

output

object type to return as. Either ‘dimObj’ (default) or ‘data.table of the embedding coordinates.

set_defaults

set default spat_unit and feat_type. Change to FALSE only when expression and spat_info are not expected to exist.

Value#

dim reduction object (default) or dim reduction coordinates
