plot_daily {iglu}

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 = "")

Arguments

data

DataFrame with column names ("id", "time", and "gl").

maxd

Default: 14. Number of days to plot. If less than 'maxd' days of data are available, all days are plotted.

LLTR

Default: 70. Lower Limit of Target Range in mg/dL.

ULTR

Default: 180. Upper Limit of Target Range in mg/dL.

inter_gap

Default: 45. The maximum allowable gap (in minutes). Gaps larger than this will not be connected in the time series plot.

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.

Value

Daily glucose time series plots for a single subject
