In arcpullr: Pull Data from an 'ArcGIS REST' API

Retrieve a table from an ArcGIS REST API

Description

This function retrieves tables present in an ArcGIS REST services API and returns them as a data frame.

Usage

get_table_layer(
  url,
  out_fields = "*",
  where = "1=1",
  token = "",
  head = FALSE,
  ...
)

Arguments

url	A character string of the url for the layer to pull
out_fields	A character string of the fields to pull for each layer
where	A character string of the where condition. Default is 1=1
token	A character string of the token (if needed)
head	Logical or numeric. Limits the number of records returned from a query. If TRUE, only the first 5 records will be returned. If numeric, then the number of records specified in head will be returned
...	Additional arguments to pass to the ArcGIS REST POST request (or associated internal functions used to query them)

Details

This function retrieves tables from an ArcGIS REST API designated by the URL. Additional querying features can be passed such as a SQL WHERE statement (where argument) as well as any other types of queries that the ArcGIS REST API accepts (using ...).

All of the querying parameters are sent via a POST request to the URL, so if there are issues with passing additional parameters via ... first determine how they fit into the POST request and make adjustments as needed. This syntax can be tricky if you're not used to it.

Value

A data frame of the appropriate layer
