getSampledVocalCountMatrix: generate vocalisation diagrams

Description

Generate a vocalisation diagram with absolute vocalisation durations.

Usage

getTurnTakingMatrix(
  df,
  begin = "begin",
  end = "end",
  nodecolumn = "role",
  individual = FALSE,
  noPauseTypes = FALSE
)

Arguments

df	a data frame consisting, minimally, of a column for vocalisation/pause start times, a column for end times, and a column identifying the speaker, speaker role or 'Floor' (for silences).
begin	the name of the column containing the start time of the vocalisation event in a row.
end	the name of the column containing the end time of the vocalisation event in the same row.
nodecolumn	the name of the column containing the node (speaker) name (e.g. 'speaker', 'role').
individual	whether to include individual speakers or group them into a single Vocalisation node
noPauseTypes	if TRUE, ignore distinctions between pauses (SwitchingPause, GrpSwitchingPause, etc)

Details

A vocalisation diagram (vocaldia) is a representation of a dialogue as a Markov process whose cell <m,n> contains the transition probability from node n to node m). Unlike getSampledVocalCountMatrix this function accummulates event durations directly, therefore resulting in no self-transitions (in general).

Value

a vocaldia object, consisting of a vocalisation matrix (vocmatrix) where cell <m,n> contains the counts of transitions from node n to node m, and a table of absolute durations of vocalisation events.
