Exports the data set of a report created on a project's 'Data Exports, Reports, and Stats' page.

The uri/url of the REDCap server typically formatted as "https://server.org/apps/redcap/api/". Required.
The user-specific string that serves as the password for a project. Required.
A single integer, provided next to the report name on the report list page. Required.
A string (either 'raw'
or 'label'
) that specifies
whether to export the raw coded values or the labels for the options of
multiple choice fields. Default is 'raw'
.
A string (either 'raw'
or 'label'
that
specifies for the CSV headers whether to export the variable/field names
(raw) or the field labels (label). Default is 'raw'
.
specifies the format of checkbox field values
specifically when exporting the data as labels. If raw_or_label
is
'label'
and export_checkbox_label
is TRUE, the values will be the text
displayed to the users. Otherwise, the values will be 0/1.
A readr::cols()
object passed internally to
readr::read_csv()
. Optional.
A boolean value indicating if all columns should be
returned as character. If true, readr::read_csv()
guesses the intended
data type for each column. Ignored if col_types
is not null.
A positive base::numeric value
passed to readr::read_csv()
that
specifies the maximum number of records to use for guessing column types.
A boolean value indicating if message
s 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.
A list of options passed to httr::POST()
.
See details at httr::httr_options()
. Optional.
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.
Currently, a list is returned with the following elements:
data
: A tibble::tibble()
of the desired records and columns.
success
: A boolean value indicating if the operation was apparently
successful.
status_code
: The
http status code
of the operation.
outcome_message
: A human readable string indicating the operation's
outcome.
elapsed_seconds
: The duration of the function.
raw_text
: If an operation is NOT successful, the text returned by
REDCap. If an operation is successful, the raw_text
is returned as an
empty string to save RAM.
