admiral 0.9.1

CRAN release: 2022-12-23

admiral 0.9.0

CRAN release: 2022-12-06

New Features

  • The new function derive_vars_joined() adds variables from an additional dataset. The selection of the observations can depend on variables from both datasets. This can be used for adding AVISIT, AWLO, AWHI based on time windows and ADY or deriving the lowest value (nadir) before the current observation (#1448).

  • New function derive_var_trtemfl() for deriving treatment emergent flags (#989)

  • The new function chr2vars() turns a character vector into a list of quosures (#1448).

  • New function derive_var_relative_flag() for flagging observations before or after a condition is fulfilled (#1453)

  • New functions get_admiral_option() and set_admiral_options() to allow more flexibility on common function inputs; e.g. like subject_keys to avoid several find and replace instances of vars(STUDYID, USUBJID). (#1338)

  • The new function create_period_dataset() for creating a reference dataset for subperiods, periods, or phases from the ADSL dataset was added. The reference dataset can be used to create subperiod, period, and phase variables in OCCDS and BDS datasets. (#1477)

  • The new function derive_vars_period() adds subperiod, period, or phase variables to ADSL. The values for the new variables are provided by a period reference dataset. (#1477)

  • New function derive_var_merged_summary() adds a variable of summarized values to the input dataset (#1564)

  • A print() method was added for all S3 objects defined by admiral, e.g., date_source(), dthcaus_source(), … (#858)

  • New metadata data set called atoxgr_criteria_ctcv5 which holds criteria for lab grading based on Common Terminology Criteria for Adverse Events (CTCAE) v5.0

  • Removed the {assertthat} dependency in admiral (#1392)

  • Removed R Version 3.6 check in CI/CD workflows in favor of the three most recent versions: 4.0, 4.1 and 4.2. (#1556)

  • The new function derive_locf_records() adds LOCF records as new observations. This can be used when the input dataset does not contain observations for missed visits/time points or when AVAL is NA for particular visits/time points (#1316).

  • New function convert_na_to_blanks() to convert character NA to blanks (#1624)

Updates of Existing Functions

  • Function derive_param_first_event() has been replaced by a more generalized derive_param_extreme_event() function with new argument mode allowing for the selection of either the "first" or "last" event record according to the conditions provided. Also the date_var argument has been replaced with the order argument instead. In addition, three new arguments new_var, true_value, and false_value have been added to allow the user to choose what variable is used to indicate whether an event happened, and the values it is given (#1317) (#1242).

  • Argument ignore_time_for_ref_end_date was added to derive_var_ontrtfl(), which controls if time is considered for the condition if start_date is after ref_end_date + ref_end_window days (#989).

  • derive_var_atoxgr_dir() default value of atoxgr_criteria_ctcv4 removed for parameter meta_criteria. Can now also choose atoxgr_criteria_ctcv5 for parameter meta_criteria, to implement NCI-CTCAEv5 grading criteria .

  • Environment objects were consolidated into a single admiral_environment object under R/admiral__environment.R. (#1572)

  • The default value of the keep_source_vars argument in create_single_dose_dataset() was updated such that it takes the values of the other arguments into account and the start_datetime and end_datetime arguments are optional now (#1598).

  • Function create_query_data() has been updated such that the dictionary version is stored in the output dataset (#1337).

CRAN release: 2022-09-05

New Features

Updates of Existing Functions

  • list_tte_source_objects() gains a package parameter and is now exported (#1212)

  • list_all_templates() and use_ad_template() gain a package parameter which can be used to indicate in which package to look for templates (#1205)

  • Randomization Date RANDDT variable added to ADSL template and vignette (#1126)

  • Renamed derive_derived_param() to derive_param_computed() and added a deprecation notice (#1229)

  • derive_vars_duration() updated to not display units when there is missing duration (#1207)

  • value_var parameter added to derive_vars_atc() (#1120)

  • format_eoxxstt_default() - Updated the default value of EOSSTT for screen failure patients (#885)

  • The imputation functions (derive_vars_dtm(), derive_vars_dt(), convert_dtc_to_dtm(), convert_dtc_to_dt()) have been enhanced to address users feedback (#1300):

    • Partial dates with missing components in the middle like "2003-12-15T-:15:18", "2003-12-15T13:-:19", "2020-07--T00:00" are handled now.

    • The control of the level of imputation has been refined by adding the highest_imputation argument. For example, highest_imputation = "D" requests imputation for day and time but not for year and month.

      (For the date_imputation and the time_imputation argument NULL is no longer a permitted value.)

    • It is now possible to impute completely missing dates by specifying highest_imputation = "Y" and the min_dates or max_dates argument.

  • order parameter added to dthcaus_source() which allows an additional character vector to be used for sorting the dataset, derive_vars_dthcaus() updated to process additional parameter (#1125).

  • create_single_dose_dataset() Fixed bug where ASTDTM and AENDTM were not updated when start_date = ASTDT and end_date = AENDT. The function has been amended to now require start_datetime and end_datetime parameters in addition to start_date and end_date.The keep_source_vars has been added to specify the variables to be retained from the source dataset (#1224)

Breaking Changes

Documentation

Various

  • derive_vars_duration() updated to not display units when there is missing duration (#1207)

  • derive_param_first_event() was updated (#1214) such that

    • AVAL is derived instead of AVALN and
    • all variables from the source dataset are kept.

  • create_single_dose_dataset() Fixed bug where ASTDTM and AENDTM were not updated when start_date=ASTDT and end_date=AENDT. The function has been amended to now require start_datetime and end_datetime parameters in addition to start_date and end_date.The keep_source_vars has been added to specify the variables to be retained from the source dataset.

  • slice_derivation() was updated such that it no longer fails if a slice is empty (#1309)

admiral 0.7.0

CRAN release: 2022-05-31

New Features

ADLB

ADPP

  • New ADPP template script available ad_adpp.R which creates Pharmacokinetics Parameters Analysis Dataset (#850)

Updates of Existing Functions

  • Datasets internal to the package have been renamed with prefix admiral_, e.g. adsl has been renamed to admiral_adsl. Corresponding SDTM datasets in {admiral.test} have also been renamed, e.g.dm to admiral_dm. These changes will impact examples, vignettes, unit tests and templates (#1108 and #1088)

  • When derive_vars_dtm_to_tm() was called for variables created by derive_vars_dtm() the function failed. This bug was fixed (#1097).

  • impute_dtc() - Fixed imputation bug. A user setting date_imputation = MID and preserve = FALSE would expect the date 2019---07 to be imputed to 2019-06-30, but the function was returning 2019-06-15. Now returns it correctly. This bug fix also addresses the issue in the downstream functions derive_vars_dt() and derive_vars_dtm(). (#1081)

  • format_eoxxstt_default() - Updated to have a more meaningful parameter name i.e. the parameter that was x is now status (#911)

Breaking Changes

  • derive_var_lstalvdt() has been deprecated in favor of derive_var_extreme_dt() (#753).

  • derive_vars_disposition_reason() now is updated such that the default is populating DCSREASP only when DSDECOD is equal to 'OTHER', which is consistent with ADaMIG_v1.3 (#886).

  • derive_vars_suppqual() has been removed from {admiral} as adding supplementary qualifiers is now done in another package called {metatools} in a function called combine_supp() and is available on CRAN (#950)

  • The filter parameter in derive_var_extreme_flag() and derive_var_worst_flag() has been deprecated in favor of restrict_derivation() (#701).

  • The following functions and parameters, which were deprecated in previous {admiral} versions, have been removed (#1056):

    • derive_agegr_ema()
    • derive_agegr_fda()
    • derive_disposition_dt()
    • derive_disposition_status()
    • derive_extreme_flag()
    • derive_worst_flag()
    • derive_obs_number()
    • derive_disposition_reason()
    • derive_var_basec()
    • derive_baseline()
    • derive_params_exposure()
    • derive_last_dose()
    • dataset parameter in lstalvdt_source and dthcaus_source

  • The following functions were deprecated in favor of derive_vars_dy() (#1076):

  • The following functions were deprecated in favor of derive_vars_merged_dtm() (#1076):

    • derive_var_trtedtm() - Derive Datetime of Last Exposure to Treatment
    • derive_var_trtsdtm() - Derive Datetime of First Exposure to Treatment

  • The derive_var_disposition_dt() function was deprecated in favor of derive_vars_merged_dt() (#1076)

  • The derive_var_atirel() function was deprecated, as it is deemed as too specific for admiral. Derivations like this can be implemented calling mutate() and case_when().
