Plot formant tracks

This function will plot formant tracks for single analyses (e.g., formants[[1]][[1]]) or comparing all candidate analyses for a single file (e.g., formants[[1]]).

plotffs(
  ffs,
  winner = NA,
  xlim = NA,
  ylim = NA,
  xlab = NA,
  ylab = NA,
  main = NA,
  colors = NA,
  cex = NA,
  lwd = NA,
  pch = NA,
  add = FALSE,
  spect = NA,
  ...
)

Arguments

ffs	a dataframe containing formant tracks for a single analysis or a list of dataframes comparing multiple analyses for a single file.
winner	an optional dataframe representing the winners file.
xlim	an optional user-specified x-axis range.
ylim	an optional user-specified y-axis range.
xlab	an optional user-specified x-axis label.
ylab	an optional user-specified y-axis label.
main	an optional user-specified plot label.
colors	an optional vector of colors to use for the formant points/lines.
cex	an optional user-specified character expansion.
lwd	an optional user-specified line width.
pch	an optional user-specified point size.
add	if FALSE, a new plot if created.
spect	an optional spectrogram to be shown behind the tracks.
...	Additional arguments are passed to the internal call of 'plot'.

Examples

if (FALSE) {
sound = readWave2("yoursound.wav")
ffs = analyze (sound)
spect = spectrogram (sound)
plotffs (ffs[[9]])
plotffs (ffs[[9]], spect = spect)
plotffs (ffs)
plotffs (ffs, spect = spect)
