Convenient Access to NYC Open Data API Endpoints.

nycOpenData

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

Version 0.1.6 now includes wrappers for 40+ NYC Open Data APIs, covering:

• 311 Service Requests
• For-Hire Vehicles (FHV)
• Juvenile Justice (rearrest rates + caseloads)
• School Discharge Reporting
• Violent & Disruptive School Incidents
• Detention Admissions
• Borough/Community District Reports
• Street Tree Census
• Urban Park Ranger Animal Condition Responses
• Permitted Events (Historical)
• and more

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

library(nycOpenData)

# Get 5,000 most recent 311 requests
data <- nyc_311(limit = 5000)

# Filter by agency and city
filtered <- nyc_311(
  limit = 2000,
  filters = list(agency = "NYPD", city = "BROOKLYN")
)

head(filtered)

About

nycOpenData makes New York City’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, nycOpenData is specifically tailored for the New York City ecosystem.

• Ease of Use: No need to hunt for 4x4 dataset IDs (e.g., erm2-nwe9); functions like nyc_311() map directly to the most popular city datasets.
• Pre-configured Logic: Wrappers include default sorting (e.g., created_date DESC) and optimized limit handling specific to NYC’s massive data volumes.
• Open Literacy: Designed specifically for students and researchers to lower the barrier to entry for civic data analysis.
