Description

Display Episode Calculation statistics for selected subject

Usage

epicalc_profile(
  data,
  lv1_hypo = 70,
  lv2_hypo = 54,
  lv1_hyper = 180,
  lv2_hyper = 250,
  dur_length = 15,
  end_length = 15,
  subject = NULL,
  dt0 = NULL,
  inter_gap = 45,
  tz = ""
)

Arguments

data

DataFrame object with column names "id", "time", and "gl". Should only be data for 1 subject. In case multiple subject ids are detected, a warning is produced and only 1st subject is used.

lv1_hypo

Numeric value specifying a hypoglycemia threshold for level 1

lv2_hypo

Numeric value specifying a hypoglycemia threshold for level 2

lv1_hyper

Numeric value specifying a hyperglycemia threshold for level 1

lv2_hyper

Numeric value specifying a hyperglycemia threshold for level 2

dur_length

Numeric value specifying the minimum duration in minutes to be considered an episode. Note dur_length should be a multiple of the data recording interval otherwise the function will round up to the nearest multiple. Default is 15 minutes to match consensus.

end_length

Numeric value specifying the minimum duration in minutes of improved glycemia for an episode to end. Default is equal to dur_length to match consensus.

subject

String corresponding to subject id

dt0

The time frequency for interpolation in minutes, the default will match the CGM meter's frequency (e.g. 5 min for Dexcom).

inter_gap

The maximum allowable gap (in minutes) for interpolation. The values will not be interpolated between the glucose measurements that are more than inter_gap minutes apart. The default value is 45 min.

tz

A character string specifying the time zone to be used. System-specific (see as.POSIXct), but " " is the current time zone, and "GMT" is UTC (Universal Time, Coordinated). Invalid values are most commonly treated as UTC, on some platforms with a warning.

Value

A plot displaying (1) the statistics for the episodes and (2) the episodes colored by level.
