Usage

PhysioEvents(
  onset = numeric(0),
  duration = numeric(0),
  type = character(0),
  value = character(0)
)

Arguments

onset

Numeric vector of event onset times in seconds.

duration

Numeric vector of event durations in seconds.

type

Character vector of event types (e.g., "stimulus", "response").

value

Character vector of event values/labels.

Value

A PhysioEvents object.
