plot_daily: Plot daily glucose profiles

Description

The function plot_daily plots daily glucose time series profiles for a single subject.

Usage

plot_daily(data, maxd = 14, LLTR = 70, ULTR = 180, inter_gap = 45, tz = "")

Value

Daily glucose time series plots 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.
