nysOpenData

nysOpenData provides simple, reproducible access to datasets from the NY State Open Data platform — directly from R, with no API keys or manual downloads required. The package is available on CRAN.

Version 0.1.3 introduces a streamlined, catalog-driven interface for NYS Open Data.

The package provides three core functions:

• nys_list_datasets() — Browse available datasets from the live nys Open Data catalog
• nys_pull_dataset() — Pull any cataloged dataset by key, with filtering, ordering, and optional date controls
• nys_any_dataset() — Pull any NYS Open Data dataset directly via its Socrata JSON endpoint

Datasets pulled via nys_pull_dataset() automatically apply sensible defaults from the catalog (such as default ordering and date fields), while still allowing user control over:

• limit
• filters
• date / from / to
• where
• order
• clean_names
• coerce_types

This redesign reduces maintenance burden, improves extensibility, and provides a more scalable interface for working with nys Open Data.

All functions return clean tibble outputs and support filtering via
filters = list(field = "value").

About

nysOpenData makes New York State’s civic datasets accessible to students,
educators, analysts, and researchers through a unified and user-friendly R interface.
Developed to support reproducible research, open-data literacy, and real-world analysis.

Comparison to Other Software

While the RSocrata package provides a general interface for any Socrata-backed portal, nysOpenData is specifically tailored for New York State Open Data.

This package is part of a broader ecosystem of tools for working with New York open data:

• nycOpenData — streamlined access to NYC Open Data
• nysOpenData — streamlined access to NY State Open Data
• mtaOpenData — streamlined access to MTA-related NY State Open Data
• chiOpenData — streamlined access to Chicago-related City Open Data
• laOpenData — streamlined access to Los Angeles-related City Open Data

Together, these packages provide a consistent, user-friendly interface for working with civic data across jurisdictions.

• Ease of Use: No need to hunt for 4x4 dataset IDs (e.g., kwxv-fwze); use catalog-based keys instead.
• Open Literacy: Designed specifically for students and researchers to lower the barrier to entry for civic data analysis.
