The function plot_daily plots daily glucose time series profiles for a single subject.
Arguments
- data
DataFrame with column names ("id", "time", and "gl").
- maxd
Number of days to plot, default is the last 14 days, or if less than 14 days of data are available, all days are plotted.
- LLTR
Lower Limit of Target Range, default value is 70 mg/dL.
- ULTR
Upper Limit of Target Range, default value is 180 mg/dL.
- inter_gap
The maximum allowable gap (in minutes). Gaps larger than this will not be connected in the time series plot. The default value is 45 minutes.
- 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.
Details
Only a single subject's data may be plotted. The black line shows the glucose values. The shaded gray area shows the target range, default 70-180 mg/dL. Areas of the curve above the ULTR are shaded yellow, while areas below the LLTR are shaded red.
