Description#

Function to set a dimension reduction slot

Usage#

set_dimReduction(
  gobject,
  dimObject,
  spat_unit = NULL,
  feat_type = NULL,
  reduction = c("cells", "genes"),
  reduction_method = c("pca", "umap", "tsne"),
  name = "pca",
  provenance = NULL,
  verbose = TRUE,
  set_defaults = TRUE
)

Arguments#

`gobject`	giotto object
`dimObject`	dimension object result to set
`spat_unit`	spatial unit (e.g. “cell”)
`feat_type`	feature type (e.g. “rna”, “dna”, “protein”)
`reduction`	reduction on cells or features
`reduction_method`	reduction method (e.g. “pca”)
`name`	name of reduction results
`provenance`	provenance information (optional)
`verbose`	be verbose
`set_defaults`	set default spat_unit and feat_type. Change to FALSE only when expression and spat_info are not expected to exist.
