grex(ensembl_id)

Arguments

ensembl_id

Character vector of Ensembl IDs

Value

This function returns a data frame with the same number of rows as the length of input Ensembl IDs, containing:

The elements that cannot be mapped will be NA.

# Ensembl IDs in GTEx v6p gene count data
data("gtexv6p")
# select 100 IDs as example
id = gtexv6p[101:200]
df = grex(id)
# Rows that have a mapped Entrez ID
df[!is.na(df$"entrez_id"),
