Examples

## Connect to the RegulonDB database if necessary
if (!exists("regulondb_conn")) regulondb_conn <- connect_database()
#> snapshotDate(): 2021-10-20

## Build the regulon db object
e_coli_regulondb <-
    regulondb(
        database_conn = regulondb_conn,
        organism = "E.coli",
        database_version = "1",
        genome_version = "1"
    )

## Obtain all the information from the "GENE" dataset
convert_to_biostrings(get_dataset(e_coli_regulondb, dataset = "GENE"))
