ligandReceptorTest

A function to perform ligand receptor analysis

ligandReceptorTest(
  sce,
  ligandReceptor_list,
  cluster,
  RNA_exprs_value = "minMax",
  use_alt_exp = TRUE,
  altExp_name = "ADT",
  altExp_exprs_value = "zi_minMax",
  num_permute = 1000,
  p_sig = 0.05
)

Arguments

sce	A singlecellexperiment object
ligandReceptor_list	A data.frame indicates the ligand receptor list
cluster	A vector indicates the cluster results
RNA_exprs_value	A character indicates which expression value for RNA in assayNames is used.
use_alt_exp	A logical vector indicates whether receptors expression will use alternative expression matrix to quantify.
altExp_name	A character indicates which expression matrix is used. by default is ADT .
altExp_exprs_value	A character indicates which expression value in assayNames is used.
num_permute	Number of permutation.
p_sig	A numeric indicates threshold of the pvalue significance

Value

A SingleCellExperiment object with ligand receptor results
