Dichotomy Index Plot

Cumulative distributions of the rest-span and active-span activity counts on a log scale, marking the active-span median and the dichotomy index I<O (the share of rest-span counts below that median). Returns a ggplot object and never errors.

Usage

plot_dichotomy(counts, rest)

Arguments

counts

Numeric activity vector.

rest

Logical (TRUE = rest), or a character state vector as accepted by dichotomy.index. Same length as counts.

Value

A ggplot object.

Examples

ts <- seq(as.POSIXct("2024-01-01", tz = "UTC"), by = 60, length.out = 2 * 1440)
h  <- as.numeric(format(ts, "%H"))
plot_dichotomy(ifelse(h >= 23 | h < 7, 5, 300), rest = h >= 23 | h < 7)
