Imputes Partial Date/Time Data Cutoff Variable (DCUTDTC)

Imputes partial date/time data cutoff variable (DCUTDTC), as required by the datacut process.

Usage

impute_dcutdtc(dsin, varin, varout)

Arguments

dsin: Name of input data cut dataframe (i.e; DCUT)
varin: Name of input data cutoff variable (i.e; DCUTDTC) which must be in ISO 8601 extended format (YYYY-MM-DDThh:mm:ss). All values of the data cutoff variable must be at least a complete date, or NA.
varout: Name of imputed output variable

Value

Returns the input data cut dataframe, with the additional of one extra variable (varout) in POSIXct datetime format, which is the imputed version of varin.

Examples

dcut <- data.frame(
  USUBJID = rep(c("UXYZ123a"), 7),
  DCUTDTC = c(
    "2022-06-23", "2022-06-23T16", "2022-06-23T16:57", "2022-06-23T16:57:30",
    "2022-06-23T16:57:30.123", "2022-06-23T16:-:30", "2022-06-23T-:57:30"
  )
)
dcut_final <- impute_dcutdtc(dsin = dcut, varin = DCUTDTC, varout = DCUTDTM)
