links: Drugs/ Carriers/ Enzymes/ Targets/ Transporters links element parser

Description

Return a list of websites that were used as references for Drugs/ Carriers/ Enzymes/ Targets/ Transporters

Usage

drugs_links(
  save_table = FALSE,
  save_csv = FALSE,
  csv_path = ".",
  override_csv = FALSE,
  database_connection = NULL
)
carriers_links(
  save_table = FALSE,
  save_csv = FALSE,
  csv_path = ".",
  override_csv = FALSE,
  database_connection = NULL
)
enzymes_links(
  save_table = FALSE,
  save_csv = FALSE,
  csv_path = ".",
  override_csv = FALSE,
  database_connection = NULL
)
targets_links(
  save_table = FALSE,
  save_csv = FALSE,
  csv_path = ".",
  override_csv = FALSE,
  database_connection = NULL
)
transporters_links(
  save_table = FALSE,
  save_csv = FALSE,
  csv_path = ".",
  override_csv = FALSE,
  database_connection = NULL
)

Value

a tibble with 4 variables:

ref-id: Name of the source website
title: Identifier for this drug in the given resource
url: The url of the website
parent_id: drug/ carrier/ target/ enzyme/ transporter id

Arguments

save_table: boolean, save table in database if true.
save_csv: boolean, save csv version of parsed tibble if true
csv_path: location to save csv files into it, default is current location, save_csv must be true
override_csv: override existing csv, if any, in case it is true in the new parse operation
database_connection: DBI connection object that holds a connection to user defined database. If save_table is enabled without providing value for this function an error will be thrown.

read_drugbank_xml_db

read_drugbank_xml_db function must be called first before any parser.

If read_drugbank_xml_db is called before for any reason, so no need to call it again before calling this function.

Examples

Run this code

if (FALSE) {
# the same parameters and usage will be applied for any parser
# return only the parsed tibble
run_all_parsers()

# will throw an error, as database_connection is NULL
run_all_parsers(save_table = TRUE)

# save in database in SQLite in memory database and return parsed tibble
sqlite_con <- DBI::dbConnect(RSQLite::SQLite())
run_all_parsers(save_table = TRUE, database_connection = sqlite_con)

# save parsed tibble as csv if it does not exist in current location,
# and return parsed tibble.
# if the csv exist before read it and return its data.
run_all_parsers(save_csv = TRUE)

# save in database, save parsed tibble as csv,
# if it does not exist in current location and return parsed tibble.
# if the csv exist before read it and return its data.
run_all_parsers(save_table = TRUE, save_csv = TRUE,
database_connection = sqlite_con)

# save parsed tibble as csv if it does not exist in given location,
# and return parsed tibble.
# if the csv exist before read it and return its data.
run_all_parsers(save_csv = TRUE, csv_path = TRUE)

# save parsed tibble as csv if it does not exist in current location and
# return parsed tibble.
# if the csv exist override it and return it.
run_all_parsers(save_csv = TRUE, csv_path = TRUE, override = TRUE)
}
