Rest-Activity Transition Curves

The rest-to-active and active-to-rest transition hazards against bout length, with a LOWESS fit and the sustained rates kRA and kAR marked. Returns a ggplot object and never errors.

Usage

plot_transitions(counts, threshold = 1, frac = 0.3)

Arguments

counts

Numeric activity vector.

threshold

Counts at or above which an epoch is active (default 1).

frac

LOWESS span (default 0.3).

Value

A ggplot object.
