data.cdc.gov URLs

For each resource ID, there are 3 relevant CDC URLs:

• resource/<id>: This redirects to the resource's main page, with displayed metadata and a data preview (e.g., data.cdc.gov/resource/ijqb-a7ye).

• api/views/<id>: This is a direct link to the underlying JSON metadata (e.g., data.cdc.gov/api/views/ijqb-a7ye).

• api/views/<id>/rows.csv: This is a direct link to the full CSV dataset (e.g., data.cdc.gov/api/views/ijqb-a7ye/rows.csv).

Examples

if (FALSE) { # \dontrun{
  pophive_download_cdc("ijqb-a7ye")
} # }
