Check if reduction loadings are present — Reduction_Loading

Check if reduction loadings are present in object and return vector of found loading names. Return warning messages for genes not found.

Reduction_Loading_Present(
  seurat_object,
  reduction_names,
  print_msg = TRUE,
  omit_warn = TRUE,
  return_none = FALSE
)

Arguments

seurat_object: object name.
reduction_names: vector of genes to check.
print_msg: logical. Whether message should be printed if all features are found. Default is TRUE.
omit_warn: logical. Whether to print message about features that are not found in current object. Default is TRUE.
return_none: logical. Whether list of found vs. bad features should still be returned if no features are found. Default is FALSE.

A list of length 3 containing 1) found features, 2) not found features.

if (FALSE) {
reductions <- Reduction_Loading_Present(seurat_object = obj_name, reduction_name = "PC_1")
found_features <- features[[1]]
