Convert gene identifiers
convertGeneIdentifiers( genes, annotation = "Homo sapiens", key = "ENSEMBL", target = "SYMBOL", ignoreDuplicatedTargets = TRUE )
genes |
Character: genes to be converted |
annotation |
|
key |
Character: type of identifier used, e.g. |
target |
Character: type of identifier to convert to; read
|
ignoreDuplicatedTargets |
Boolean: if |
Character vector of the respective targets of gene identifiers. The
previous identifiers remain other identifiers have the same target (in case
ignoreDuplicatedTargets = TRUE
) or if no target was found.
