mtaOpenData

mtaOpenData provides simple, reproducible access to MTA-related datasets from the
NY State Open Data portal platform — directly from R,
with no API keys or manual downloads required. Working directly with Socrata APIs can be cumbersome — mtaOpenData simplifies this process into a clean, reproducible workflow.

Version 0.1.0 introduces a streamlined, catalog-driven interface for MTA Open Data.

The package provides three core functions:

• mta_list_datasets() — Browse available datasets from the live MTA Open Data catalog
• mta_pull_dataset() — Pull any cataloged dataset by key, with filtering, ordering, and optional date controls
• mta_any_dataset() — Pull any MTA Open Data dataset directly via its Socrata JSON endpoint

Datasets pulled via mta_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 MTA Open Data.

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

Example

library(mtaOpenData)

bus_stops <- mta_pull_dataset(dataset = "mta_bus_stops", limit = 5000)

head(bus_stops)

About

mtaOpenData 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, mtaOpenData 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

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., 2ucp-7wg5); use catalog-based keys instead.
• Open Literacy: Designed specifically for students and researchers to lower the barrier to entry for civic data analysis.
