Load Any Los Angeles Open Data Dataset

Description

Downloads any Los Angeles Open Data dataset given its Socrata JSON endpoint.

Usage

la_any_dataset(
  json_link,
  limit = 10000,
  timeout_sec = 30,
  clean_names = TRUE,
  coerce_types = TRUE
)

Arguments

json_link

A Socrata dataset JSON endpoint URL (e.g., "https://data.lacity.org/resource/6rrh-rzua.json.json").

limit

Number of rows to retrieve (default = 10,000).

timeout_sec

Request timeout in seconds (default = 30).

clean_names

Logical; if TRUE, convert column names to snake_case (default = TRUE).

coerce_types

Logical; if TRUE, attempt light type coercion (default = TRUE).

Value

A tibble containing the requested dataset.

Examples

# Examples that hit the live Los Angeles Open Data API are guarded so CRAN checks
# do not fail when the network is unavailable or slow.
if (interactive() && curl::has_internet()) {
  endpoint <- "https://data.lacity.org/resource/6rrh-rzua.json.json"
  out <- try(la_any_dataset(endpoint, limit = 3), silent = TRUE)
  if (!inherits(out, "try-error")) {
    head(out)
  }
}

List datasets available in laOpenData

Description

Retrieves the current Open NY catalog and returns datasets available for use with 'la_pull_dataset()'.

Usage

la_list_datasets()

Details

Keys are generated from dataset names using 'janitor::make_clean_names()'.

Value

A tibble of available datasets, including generated 'key', dataset 'id', and dataset 'name'.

Examples

if (interactive() && curl::has_internet()) {
  la_list_datasets()
}

Pull a Los Angeles Open Data dataset from the Los Angeles Open Data catalog

Description

Uses a dataset 'key' or 'id' from 'la_list_datasets()' to pull data from Los Angeles Open Data.

Usage

la_pull_dataset(
  dataset,
  limit = 10000,
  filters = list(),
  date = NULL,
  from = NULL,
  to = NULL,
  date_field = NULL,
  where = NULL,
  order = NULL,
  timeout_sec = 30,
  clean_names = TRUE,
  coerce_types = TRUE
)

Arguments

dataset

A dataset key or ID from 'la_list_datasets()'.

limit

Number of rows to retrieve (default = 10,000).

filters

Optional named list of filters. Supports vectors (translated to IN()).

date

Optional single date (matches all times that day) using 'date_field'.

from

Optional start date (inclusive) using 'date_field'.

to

Optional end date (exclusive) using 'date_field'.

date_field

Optional date/datetime column to use with 'date', 'from', or 'to'. Must be supplied when 'date', 'from', or 'to' are used.

where

Optional raw SoQL WHERE clause. If 'date', 'from', or 'to' are provided, their conditions are AND-ed with this.

order

Optional SoQL ORDER BY clause.

timeout_sec

Request timeout in seconds (default = 30).

clean_names

Logical; if TRUE, convert column names to snake_case (default = TRUE).

coerce_types

Logical; if TRUE, attempt light type coercion (default = TRUE).

Details

Dataset keys are generated from dataset titles using 'janitor::make_clean_names()'. Because keys are derived from live catalog metadata, dataset IDs are the more stable option.

Value

A tibble.

Examples

if (interactive() && curl::has_internet()) {
  # Pull by key
  la_pull_dataset("current_employee_names_salaries_and_position_titles", limit = 3)

  # Pull by ID
  la_pull_dataset("xzkq-xp2w", limit = 3)

  # Filters
  la_pull_dataset("xzkq-xp2w", limit = 3, filters = list(salary_or_hourly = "HOURLY"))

}
