opendatasus_arquivos: Expand downloadable files from OpenDataSUS resources

In datasus: An Interface to Brazilian Public Health Data

Expand downloadable files from OpenDataSUS resources

Description

Some OpenDataSUS resources, notably state-level influenza-like illness datasets, publish several file parts as links inside the resource description instead of the primary URL field. This function expands both representations to one row per downloadable file.

Usage

opendatasus_arquivos(
  conjunto,
  recurso = NULL,
  formato = NULL,
  cache = TRUE,
  atualizar = FALSE
)

Arguments

conjunto	Dataset slug returned by [opendatasus_catalogo()].
recurso	Optional exact resource name or identifier.
formato	Optional resource format.
cache	Whether to cache portal metadata for the duration controlled by option 'datasus.cache_ttl'.
atualizar	Whether to ignore cached metadata and query the portal again.

Value

A data frame with one row per downloadable file and its parent resource identifier, part number and URL.

Examples

old_options <- options(
  datasus.timeout = 5,
  datasus.download_timeout = 15,
  datasus.max_tries = 1
)
try({
opendatasus_arquivos(
  "notificacoes-de-sindrome-gripal-leve-2024",
  recurso = "Dados MS - 20/12",
  formato = "CSV"
)
})
