In tinyarray: Expression Data Analysis and Visualization

trans_ensembl_exp

Description

Transform rownames of an expression set from Ensembl IDs to gene symbols using the latest gene annotation.

Usage

trans_ensembl_exp(
  exp,
  mrna_only = FALSE,
  lncrna_only = FALSE,
  species = "human",
  average = FALSE
)

Arguments

exp	expression matrix with Ensembl IDs as rownames
mrna_only	only keep mrna rows in result
lncrna_only	only keep lncrna rows in result
species	choose human, mouse, or rat; default is human
average	logical, if TRUE, average rows that map to the same target symbol; if FALSE, keep the first matched row for each symbol.

Value

a transformed expression set with symbol
