rc_import | R Documentation |
Imports records from a data.frame
to a REDCap Database
rc_import(
record_data,
url = getOption("redcap_bundle")$redcap_url,
token = getOption("redcap_token"),
data_dict = getOption("redcap_bundle")$data_dict,
overwriteBehavior = "normal",
returnContent = "count",
returnData = FALSE,
logfile = "",
batch_size = -1
)
record_data |
A |
url |
A url address to connect to the REDCap API |
token |
Path to a text file containing your REDCap API token |
data_dict |
Dataframe. A REDCap project data dictionary. By default,
$data_dict is expected in the REDCap bundle option, as created by
|
overwriteBehavior |
Character string. 'normal' prevents existing data in REDCap from being altered. Note that when set to 'overwrite', blank values (NAs) will replace existing data. |
returnContent |
Character string. 'count' returns the number of records imported; 'ids' returns a list of record ids imported; 'nothing' returns no message. |
returnData |
Logical. Prevents the REDCap import and instead returns the data frame that would have been given for import. This is sometimes helpful if the API import fails without providing an informative message. The data frame can be written to a csv and uploaded using the interactive tools to troubleshoot the problem. Please shoot me an e-mail if you find errors I haven't accounted for. |
logfile |
An optional filepath (preferably .txt) in which to print the
log of errors and warnings about the data.
If |
batch_size |
Specifies size of batches. A negative value indicates no batching. |
A record of imports through the API is recorded in the Logging section of the project.
rc_import
prevents the most common import errors by testing the
data before attempting the import. Namely
Check that all variables in record_data
exist in the REDCap data data_dictionary.
Check that the study id variable exists
Force the study id variable to the first position in the data frame (with a warning)
Remove calculated fields (with a warning)
Verify that REDCap date fields are represented in the data frame as either character, POSIXct, or Date class objects.
Determine if values are within their specified validation limits.
See the documentation for validateImport
for detailed
explanations of the validation.
