derive_disposition_dt(
  dataset,
  dataset_ds,
  new_var,
  dtc,
  filter_ds,
  date_imputation = NULL,
  subject_keys = vars(STUDYID, USUBJID)
)

Arguments

dataset

Input dataset

dataset_ds

Datasets containing the disposition information (e.g.: ds)

It must contain:

  • STUDYID, USUBJID,

  • The variable(s) specified in the dtc

  • The variables used in filter_ds.

new_var

Name of the disposition date variable

a variable name is expected

dtc

The character date used to derive/impute the disposition date

A character date is expected in a format like yyyy-mm-dd or yyyy-mm-ddThh:mm:ss. If the year part is not recorded (missing date), no imputation is performed.

filter_ds

Filter condition for the disposition data.

Filter used to select the relevant disposition data. It is expected that the filter restricts dataset_ds such that there is at most one observation per patient. An error is issued otherwise.

Permitted Values: logical expression.

date_imputation

The value to impute the day/month when a datepart is missing.

If NULL: no date imputation is performed and partial dates are returned as missing.

Otherwise, a character value is expected, either as a

  • format with day and month specified as 'mm-dd': e.g. '06-15' for the 15th of June

  • or as a keyword: 'FIRST', 'MID', 'LAST' to impute to the first/mid/last day/month.

Default is NULL

subject_keys

Variables to uniquely identify a subject

A list of quosures where the expressions are symbols as returned by vars() is expected.

Value

the input dataset with the disposition date (new_var) added
