Plot formant contours — ft.lines • fasttrackr

Draws lines representing formant contours using the information represented in aggregated data files. Colors are taken from the 'color' column in the data.

ft.lines(
  aggregated_data,
  xformant = 1,
  yformant = 2,
  revaxes = FALSE,
  logaxes = FALSE,
  lwd = 2,
  starttime = 0,
  endtime = 0,
  add = FALSE,
  ...
)

Arguments

aggregated_data	A dataframe containing the data from an 'aggregated_data' file produced by Fast Track.
xformant	an integer indicating which formant number should be plotted on the x axis.
yformant	an integer indicating which formant number should be plotted on the y axis.
revaxes	if TRUE, axis ranges are inverted so that they go high > low.
logaxes	if TRUE, axes are logarithmic.
lwd	an integer determining contour line width.
starttime	an integer indicating which time point the contour should start at.
endtime	an integer indicating which time point the contour should end at.
add	if FALSE, a new plot if created.
...	Additional arguments are passed to the internal call of 'lines'.
