retrieveSCEIndex: Retrieve cell/feature index by giving identifiers saved in...

In singleCellTK: Comprehensive and Interactive Analysis of Single Cell RNA-Seq Data

Description

Originally written in retrieveFeatureIndex. Modified for also retrieving cell indices and only working for SingleCellExperiment object. This will return indices of features among the rowData/colData. Partial matching (i.e. grepping) can be used.

Usage

retrieveSCEIndex(
  inSCE,
  IDs,
  axis,
  by = NULL,
  exactMatch = TRUE,
  firstMatch = TRUE
)

Arguments

inSCE	Input SingleCellExperiment object. Required
IDs	Character vector of identifiers for features or cells to find in rowData or colData of inSCE
axis	A character scalar to specify whether to search for features or cells. Use "row", "feature" or "gene" for features; "col" or "cell" for cells.
by	Character. In which column to search for features/cells in rowData/colData. Default NULL for search the rownames/colnames
exactMatch	A logical scalar. Whether to only identify exact matches or to identify partial matches using grep. Default TRUE
firstMatch	A logical scalar. Whether to only identify the first matches or to return all plausible matches. Default TRUE

Value

A unique, non-NA numeric vector of indices for the matching features/cells in inSCE.
