featureIndex {singleCellTK} | R Documentation |
This will return indices of features among the rownames
or rowData of a data.frame, matrix, or a SummarizedExperiment
object including a SingleCellExperiment.
Partial matching (i.e. grepping) can be used by setting
exactMatch = FALSE
.
featureIndex( features, inSCE, by = "rownames", exactMatch = TRUE, removeNA = FALSE, errorOnNoMatch = TRUE, warningOnPartialMatch = TRUE )
