REDCapR (version 1.2.0)

redcap_dag_read: Read data access groups from a REDCap project

Description

This function reads all available data access groups from REDCap an returns them as a tibble::tibble().

Usage

redcap_dag_read(
  redcap_uri,
  token,
  http_response_encoding = "UTF-8",
  locale = readr::default_locale(),
  verbose = TRUE,
  config_options = NULL,
  handle_httr = NULL
)

Value

Currently, a list is returned with the following elements:

• data: A tibble::tibble() of all data access groups of the project.

• success: A boolean value indicating if the operation was apparently successful.

• status_codes: A collection of http status codes, separated by semicolons. There is one code for each batch attempted.

• outcome_messages: A collection of human readable strings indicating the operations' semicolons. There is one code for each batch attempted. In an unsuccessful operation, it should contain diagnostic information.

• elapsed_seconds: The duration of the function.

Arguments

redcap_uri

The uri/url of the REDCap server typically formatted as "https://server.org/apps/redcap/api/". Required.

token

The user-specific string that serves as the password for a project. Required.

http_response_encoding

The encoding value passed to httr::content(). Defaults to 'UTF-8'.

locale

a readr::locale() object to specify preferences like number, date, and time formats. This object is passed to readr::read_csv(). Defaults to readr::default_locale().

verbose

A boolean value indicating if messages should be printed to the R console during the operation. The verbose output might contain sensitive information (e.g. PHI), so turn this off if the output might be visible somewhere public. Optional.

config_options

A list of options passed to httr::POST(). See details at httr::httr_options(). Optional.

handle_httr

The value passed to the handle parameter of httr::POST(). This is useful for only unconventional authentication approaches. It should be NULL for most institutions. Optional.
