Detect time anomalies

Function detecting time anomalies, which can refer to activities with negative or zero duration

detect_time_anomalies(
  activitylog,
  anomaly_type = c("both", "negative", "zero"),
  details = TRUE,
  filter_condition = NULL
)

Arguments

activitylog	The activity log
anomaly_type	Type of anomalies that need to be detected (either "negative", "zero" or "both")
details	Boolean indicating wheter details of the results need to be shown
filter_condition	Condition that is used to extract a subset of the activity log prior to the application of the function

Value

activitylog containing the rows of the original activity log for which a negative or zero duration is detected, together with the duration value and whether it constitutes a zero or negative duration

Examples

# \donttest{
data("hospital_actlog")
detect_time_anomalies(activitylog = hospital_actlog)
#> Selected anomaly type: both
#> *** OUTPUT ***
#> For 5 rows in the activity log (9.43%), an anomaly is detected.
#> The anomalies are spread over the activities as follows:
#> # A tibble: 3 x 3
#> # Groups:   activity [3]
#>   activity      type                  n
#>   <chr>         <chr>             <int>
#> 1 Registration  negative duration     3
#> 2 Clinical exam zero duration         1
#> 3 Trage         negative duration     1
#> Anomalies are found in the following rows:
#> # A tibble: 5 x 9
