Function for plotting pitch objects called by praatpicture. Instead of
using this function directly, just use
praatpicture('my_sound_file', frames='pitch').

PitchTier object loaded using rPraat::pt.read
Start time (in seconds) of desired plotted area.
End time (in seconds) of desired plotted area.
Logical; should time on the x-axis run from 0 or from the
original time? Default is TRUE.
Logical; should dotted lines be plotted corresponding to
locations in a TextGrid? Default is FALSE.
Numeric vector giving locations in seconds of locations from
a TextGrid to be plotted with dotted lines. Default is NULL.
String or vector of strings giving the color(s) to
use for plotting focus tier lines. If multiple tiers are focused, a vector
of the same length can be passed, and the nth tier will be plotted in the
nth color. Default is 'black'.
String or vector of strings giving the line
type(s) for plotting focus tier lines. If multiple tiers are focused, a
vector of the same length can be passed, and the nth tier will be plotted in
the nth line type. Default is 'dotted'.
String giving the type of pitch plot to produce; default
is draw (a line plot), the only other option is speckle (a point plot).
Alternatively a vector c('draw','speckle') can be passed, in which case
both are used.
String giving the frequency scale to use when producing
pitch plots. Default is hz; other options are logarithmic (also in Hz),
semitones, erb, and mel.
Vector of two integers giving the frequency range to be
used for producing pitch plots. Default is NULL, in which case the pitch
range is automatically reset to c(-12,30) for the semitones scale,
c(0,10) for the erb scale, and c(50,500) for the Hz-based scales,
following Praat defaults.
Frequency in Hz giving the reference level for converting
pitch frequency to semitones. Default is 100.
String giving the name of the color to be used for
plotting pitch. Default is 'black'.
Integer indexing waveform relative to other plot components.
Default is NULL.
Logical; should only minimum and maximum values be given
on the y-axis? Default is TRUE. Can also be a logical vector if some but
not all plot components should have minimum and maximum values on the y-axis.
Ignored for TextGrid component.
Named list giving parameters for differential
highlighting of pitch based on the time domain. This list
should contain information about which parts of the plot to highlight, either
done with the start and end arguments which must be numbers or numeric
vectors, or using the tier and label arguments to highlight based on
information in a plotted TextGrid. Further contains the optional arguments
color (string or vector of strings, see color),
drawSize or speckleSize (both numeric), and background
(a string specifying a background color).
String giving the name of the label to print along the
y-axis when printing a pitch track. Default is NULL, in which case the
axis label will depend on the scale.
Number indicating the line width if
plotType is 'draw'. Default is 1. Controls the lwd argument of
graphics::lines.
Number indicating the point size of if _plotType is
'speckle'. Default is 1. Controls the cex arguments of
graphics::points.
