Reorder idents by the gene expression

Usage

srt_reorder(
  srt,
  features = NULL,
  reorder_by = NULL,
  layer = "data",
  assay = NULL,
  log = TRUE,
  distance_metric = "euclidean",
  verbose = TRUE
)

Arguments

srt: A Seurat object.
features: Features to plot: a character vector or a named list of assay gene names or numeric metadata columns.
reorder_by: Reorder groups instead of idents.
layer: Assay layer to use.
assay: Assay to use. NULL uses the default assay.
log: Whether log1p transformation needs to be applied.
distance_metric: Metric to compute distance.
verbose: Whether to print the message. Default is TRUE.
