transfer_labels: Transfer labels from the reference to the query data set

In quadbiolab/simspec: Calculate data representation of Reference/Cluster Similarity Spectrum

Transfer labels from the reference to the query data set

Description

A kNN classifier is used to predict labels of the query data, given the reference data with the same data representation

Usage

transfer_labels(
  data_ref = NULL,
  data_query = NULL,
  knn_ref_query = NULL,
  label_ref,
  k = 50,
  thres_prop_match = 0.5,
  return_all = FALSE,
  verbose = TRUE
)

Arguments

data_ref	Reference data matrix
data_query	Query data matrix
knn_ref_query	KNN matrix, where each row represents one sample in the query data, and each column represents one nearest neighbors in the reference data. If NULL, it is calculated using data_ref and data_query
label_ref	Class labels of each sample in the reference
k	Number of neighbors for classification
thres_prop_match	If no class gets higher supported proportion than this value, the prediction fails for the query sample and NA is returned
return_all	Whether to return all results including the transferred labels and the kNN proportions. Only the transferred labels are returned when it is FALSE
verbose	Whether to output the verbose message

Value

A vector of the predicted/transferred labels of the query data
