Combined function to compare scRNA-seq data to bulk RNA-seq data and marker list

Usage

clustify_nudge(input, ...)

# S3 method for default
clustify_nudge(
  input,
  ref_mat,
  marker,
  metadata = NULL,
  cluster_col = NULL,
  query_genes = NULL,
  compute_method = "spearman",
  weight = 1,
  threshold = -Inf,
  dr = "umap",
  norm = "diff",
  call = TRUE,
  marker_inmatrix = TRUE,
  mode = "rank",
  obj_out = FALSE,
  seurat_out = obj_out,
  rename_prefix = NULL,
  lookuptable = NULL,
  ...
)

# S3 method for Seurat
clustify_nudge(
  input,
  ref_mat,
  marker,
  cluster_col = NULL,
  query_genes = NULL,
  compute_method = "spearman",
  weight = 1,
  obj_out = TRUE,
  seurat_out = obj_out,
  threshold = -Inf,
  dr = "umap",
  norm = "diff",
  marker_inmatrix = TRUE,
  mode = "rank",
  rename_prefix = NULL,
  ...
)

Arguments

input

express matrix or object

...

passed to matrixize_markers

ref_mat

reference expression matrix

marker

matrix of markers

metadata

cell cluster assignments, supplied as a vector or data.frame. If data.frame is supplied then cluster_col needs to be set.

cluster_col

column in metadata that contains cluster ids per cell. Will default to first column of metadata if not supplied. Not required if running correlation per cell.

query_genes

A vector of genes of interest to compare. If NULL, then common genes between the expr_mat and ref_mat will be used for comparision.

compute_method

method(s) for computing similarity scores

weight

relative weight for the gene list scores, when added to correlation score

threshold

identity calling minimum score threshold, only used when obj_out = T

dr

stored dimension reduction

norm

whether and how the results are normalized

call

make call or just return score matrix

marker_inmatrix

whether markers genes are already in preprocessed matrix form

mode

use marker expression pct or ranked cor score for nudging

obj_out

whether to output object instead of cor matrix

seurat_out

output cor matrix or called seurat object (deprecated, use obj_out)

rename_prefix

prefix to add to type and r column names

lookuptable

if not supplied, will look in built-in table for object parsing

Value

single cell object, or matrix of numeric values, clusters from input as row names, cell types from ref_mat as column names

    cluster_col = "seurat_clusters",
    threshold = 0.8,
    obj_out = FALSE,
    mode = "pct",
    dr = "umap"
