subset_time: select subset of elan or rttm annotations

In gobbios/avutils: various utilities for DiViMe tools and audio processing

Description

select subset of elan or rttm annotations

Usage

subset_time(x, from = NULL, to = NULL, include_incomplete = TRUE,
  shift_times = FALSE)

Arguments

x	a data.frame (result from read_elan or read_rttm)
from	numeric, include annotations from this point forward (by default NULL, i.e. take everything from the first line of the data)
to	numeric, include annotations up to that point (by default NULL, i.e. take up to the last line)
include_incomplete	logical, should annotations that cross from = and/or to = be kept (by default TRUE)
shift_times	logical, not implemented (yet)

Details

If you keep annotations that cross the from and/or to boundaries, the durations of those annotations will be updated.

Value

a data.frame

Examples

rttm <- system.file("yunitator_old_synthetic_speech_overlap.rttm", package = "avutils")
x <- read_rttm(rttm)
# leave unchanged
subset_time(x)
# up to 26
subset_time(x, to = 26)
# remove incomplete anno (25.6 - 26.3)
subset_time(x, to = 26, include_incomplete = FALSE)

elan <- system.file("synthetic_speech_overlap.eaf", package = "avutils")
x <- read_elan(elan)
# leave unchanged
subset_time(x)
# up to 29
subset_time(x, to = 29)
# remove incomplete anno (28.3 - 30.5)
subset_time(x, to = 29, include_incomplete = FALSE)
