redcapAPI 2.7.1 (2023-06-12)

Version bump for CRAN publication

redcapAPI 2.7.0

• The new function exportRecordsTyped is now available as a replacement for the existing exportRecords. It is a breaking change in interface--but provides far better stability in calling--full inversion of control over casting, retries through the connection object, and a clear error report as part of the final dataframe. Please take a moment to read the documentation on exportRecordsTyped and start moving over to using it over exportRecords.
• bundle argument has been removed from all API methods. (It is no longer needed, thanks to caching). Backward compatibility is unaffected.
• Introduces the offlineConnection function, which creates the redcapOfflineConnection object. This connection object can be built using either data frames structured like those received from the API methods, or the CSV files downloaded from the REDCap UI. The object function in the same way as an API connection with caching. Meta data can be retrieved via rcon$metadata(), etc..
• added castForImport. Recasts a data.frame back into the expected text values.
• added exportReportsTyped. Similar to exportRecordsTyped. * Helper function exportBulkRecords for bulk calls to exportRecordsTyped.

redcapAPI 2.6.2

• Added retry parameter to connection object. On timeouts and gateway failures it retries 5 times now by default.
• Cleanup from emergency patches.

redcapAPI 2.6.1

• Emergency fix. REDCap latest version changed its API calling syntax.
• Fix to choice name parsing when only a single choice is specified.
• Fix to importMethod validators when event=NULL

redcapAPI 2.6.0

• A set of functions to deal with file import / export in REDCap
  • exportFileRepositoryListing
  • exportFromFileRepository
  • exportFileRepository
  • importToFileRepository
  • deleteFromFileRepository
  • createFileRepositoryFolder
  • importFileRepository
  • deleteFileRepository

redcapAPI 2.5.0 (2023-03-24)

• IMPORTANT: The upcoming 3.0.0 release will be a breaking change for exportRecords. This is needed for full inversion of control to the user over type casting.
• Fully removed deprecated redcapDbConnection
• Added a drop= argument to exportRecords and exportReports. These columns are dropped before returning.
• Metadata is cached in the connection object. In addition to token, url, and config elements, the following are also made available:
  • metadata
  • arms
  • events
  • fieldnames
  • mapping
  • users
  • version
  • projectInformation each of these has a companion function
  • has_* (returns a logical indicating if the element has been cached)
  • flush_* (removes the cached value)
  • refresh_* (replaces the cached value with a fresh call to the API) There are also flush_all and refresh_all methods.
• New method: exportLogging
• Fixed minor bugs in validations and improved documentation
• Fixed bug in formatting vectors for API calls in multiple places #33
• Removed stringr and tidyr as dependencies
• Removed unused version argument from checkbox_suffix
• Fixed error thrown in export_users when labels=TRUE

• Fixed bug date handling for NA in date conversion of time_hh_mm_ss

redcapAPI 2.4.0 (2023-03-01)

• Added handlers overrides for type conversion based on REDCap field type.

redcapAPI 2.3.3 (2023-01-26)

Transfer from Benjamin Nutter to VUMC Biostatistics.

redcapAPI 2.3.0

• Bug fix: Unmapped suffixes do not cause crashes, only warnings.

redcapAPI 2.2.0

• BREAKING CHANGE: The dev_allocate and prod_allocate elements of the object returned by allocationTable have been named dev_allocation and prod_allocation, respectively.
• Bug fix: importRecords now handles data with repeating forms correctly.
• New feature: UTF-8 Characters may be stripped from the data dictionary.

redcapAPI 2.1.0

• Bug fix: Add [form]_complete fields
• Bug fix: Include [form]_complete fields in Reports
• New feature: [form]_complete fields may be explicitly requested.
• New feature: Automatic selection of [form]_complete fields may be turned off.

redcapAPI 2.0.0

• redcapDbConnection methods are being deprecated. To our knowledge, no one is using these methods, and we do not believe they would work as previously coded anyway. The methods definitions continue to be reserved although they will likely not be developed in the foreseeable future (if at all). Please file an issue on GitHub if you feel such methods would be of use.
• redcapProjectInfo is being deprecated, as it will inevitably create confusion with the API method exportProjectInformation. The replacement function is exportBundle.
• export bundles are now placed into the option redcap_bundle by default. For now, exportBundle will also return that same object. This is to prevent back-compatibility problems with existing code but will change at a future date.
• Added several new API functions. All functions up to REDCap 6.5.0 are included.
• Optional arguments that previously had no default now default to NULL. There should be no change in behavior related to this change.
• Further standardization to documentation. Each function has three new sections: "From the REDCap Documentation" which gives the description of the function as taken from the REDCap documentation; "REDCap Version" which gives the versions of REDCap for which the function is known to operate; and "Known REDCap Limitations" which documents any bugs or other limitations that may be encountered when working with the API
• the fieldToVar function now operates on a switch statement instead of a sequence of if else blocks. It also incorporates a for loop in place of the lapply and <<- structure.
• Error checking, when feasible, makes use of the checkmate package.
• exportVersion will now return "5.12.2" for all versions of REDCap less than 6.0.0. While it is admittedly odd, this allows for consistent logical comparisons of of versions and allows better control of the package's behavior over multiple versions of REDCap.
• REDCap variables that can reasonably be treated as factors are given an additional class, redcapFactor, that inherits whatever class the variable becomes on export. For example, if factors = TRUE, the new class will be c("redcapFactor", "factor"), otherwise, it may be something similar to c("redcapFactor", "numeric"). This is done to assist in converting factors back and forth between classes as needed (particular when using redcapFactorFlip).
• A package option is added for how to manage errors returned by the API. This is used to assist in dealing with errors relating to bugs in the API and/or the user's version of REDCap. For instance, if an API method doesn't exist for the user's version of REDCap, the user can control if a hard error is returned, or if a NULL value is returned. See ?redcap_error for details.
• Codebase has been standardized and given a cleaner format (yeah, that's totally subjective)

redcapAPI 1.3.5

• Bug fixes from @tobadia. (Issue #79)

redcapAPI 1.3.2

• Bug fix. Changed the call to fieldToVar in exportReports; was incorrectly referencing the meta_data field names. Thanks to Will Campbell for finding this bug.

redcapAPI 1.3.1

• Changed the default config argument in redcapConnection from config=list() to config=httr::config().
  • Added code to allow all errors from apiCall to be returned correctly.

redcapAPI 1.3 (2015-03-14)

• The Maintainer has been changed to Stephen Lane
  • Bug fix: The REDCap API Error message for exportEvents, exportArms, and exportMappings changed between versions 5.x and 6.0. In 5.x, the error message is "You cannot export arms for classic projects." In 6.0+, it is "ERROR: You cannot export arms for classic projects." The change causes exportEvents, exportArms, and exportMappings to cast an error instead of returning the character string with the error. The bug fix accommodates the error messages from both 5.x and 6.0+.

redcapAPI 1.2 (2015-01-16)

• Code has been rewritten to make use of the roxygen2 documentation style.
  • The function 'allocationTable' is added. This assists in producing allocation tables for the randomization module.
  • Offline versions for 'exportRecords' and 'allocationTable' are included. These produce output identical to the API calls, but operate based on the csv's downloaded via the user interface.

redcapAPI 1.1 (2014-11-25)

• redcapAPI now depends on R 3.0.0 or higher
  • A bug fix was added. When specifying the 'fields' and 'forms' arguments in 'exportRecords', only the variables in 'fields' were being converted to the appropriate data types. This has been corrected.
  • redcapAPI requires Hmisc 3.14-6 or higher. This is a consequence of the following item. Please update your Hmisc package.
  • The Hmisc package was moved from the Suggests field to the Imports field. This reflects the addition of some of the label functions in Hmisc being explicitly exported, making them available to import.

redcapAPI 1.0.1 (2014-10-21)

• Bug fix: in importRecords meta data was not previously exported when a project info object was not provided. This is now corrected
  • Bug fix: in exportRecords and exportReports, the checkbox labels weren't being returned as factor levels when checkboxLabels=TRUE. The behavior is now consistent with expectations.
  • Bug fix: in compareRedcapVersion, a logical check was failing due to an omitted argument in grepl. This has been corrected.
  • added function apiCall. This wraps a call to tryCatch. If a Gnu/TLS recv error is returned, the encoding is changed from 'gzip' to 'identity' to successfully retrieve the API response.
  • tryCatch calls are added to redcapProjectInfo to prevent fatal errors when one of the API functions casts an error. The output is modified to indicate where the problem occurred. This is most likely to affect exportUsers. An unresolved issue behind this is logged in the issues on GitHub.
