laOpenData

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

Version 0.1.1 introduces a streamlined, catalog-driven interface for Los Angeles Open Data, extending the open data ecosystem beyond New York to support cross-city analysis and comparative civic research.

The package provides three core functions:

• la_list_datasets() — Browse available datasets from the live Los Angeles Open Data catalog
• la_pull_dataset() — Pull any cataloged dataset by key, with filtering, ordering, and optional date controls
• la_any_dataset() — Pull any Los Angeles Open Data dataset directly via its Socrata JSON endpoint

Datasets pulled via la_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 Los Angeles Open Data.

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

Installation

Development version (GitHub)

devtools::install_github("nyc-open-data-lab/laOpenData")

Example

library(laOpenData)

la_vacent_buildings <- la_pull_dataset(
  dataset = "building_safety",
  limit = 1000
)

About

laOpenData makes Los Angeles’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, laOpenData is specifically tailored for Los Angeles Open Data Portal.

This package is part of a broader ecosystem of tools for working with 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

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.
