splice_time.Metre.Rd

Generate spliced timeline using a Metre object

Usage

# S3 method for Metre
splice_time(
  x,
  window_duration = NULL,
  window_proportion = NULL,
  tactus = NULL,
  ...
)

Arguments

x

Metre object.

window_duration

duration of window around beat (may lead to overlapping windows if large).

window_proportion

sets the window duration around beat based on a proportion (0, 0.5] of the gap to the previous and following cycles. The first and last beats in each Metre are removed.

tactus

vector of Metres to subset on.

...

ignored.

Value

a Splice object.
