praatpicture 1.3.0

Added the drawSize and speckleSize arguments, which respectively control the line widths of plot components where the _plotType is 'draw' and the point sizes of plot components where the _plotType is 'speckle'.
Added the wave_lineWidth argument which controls the line width of the waveform.
Added the tUnit argument for controlling the time unit printed along the x-axis. The default is still time in seconds, but when tUnit = 'ms', the time unit is milliseconds. The time_axisLabel argument will by default reflect the unit specified in tUnit, but the axis label can still be controlled by the user.
Added the formant_number argument which determines the number of formants to include in a plot (independently of formant_maxN, which determines the number of formants to track if no .Formant file is provided). By default, all available formants are plotted.
Added the mainTitleAlignment argument which controls the vertical alignment of the plot title.
Added support for all the above features in shiny_praatpicture()
Fixed a bug that made it impossible to plot 24-bit WAV files.

praatpicture 1.2.4

Added the option to plot read and plot Pitch files with the .Pitch extension generated in R in addition to PitchTier files with the .PitchTier extension. If a .Pitch file is available with the same base name as the plotted sound file, this is now by default used to when plotting pitch unless a .PitchTier file is also available. Plotting a .Pitch file is likely somewhat slower than plotting a .PitchTier file, but they are simpler to generate and this fixes the bug where plotting .PitchTier files with pitch_plotType = 'draw' would linearly extrapolate pitch in unvoiced regions.

Added Blackman as a possible option to spec_windowShape. Blackman windows were already available in phonTools::windowfunc() which is used to generate windows for spectrogram estimation. These weren’t originally used by praatpicture() as they’re not implemented in Praat, but I decided to add them because the Gaussian windows used by phonTools::windowfunc() don’t behave the same as Praat. If you the spectrogram of a simple sine wave using the Gaussian windows, sidelobes (horizontal lines) are clearly visible in the spectrogram; these are artefacts of the windowing and should theoretically not be there when using Gaussian windows (at least according to the Praat documentation), but for some reason they are.
Increased the upload limit for the Shiny server to approx 50 MB.

Added talking argument to emupicture(), allowing users to make talking_praatpicture() plots with embedded audio directly from an EMU database.

Shiny support has been added with the shiny_praatpicture() function.
The proportion argument no longer has to add up to 100.
Users can now specify the location of a .TextGrid file when plotting annotations.

It’s now possible to change font sizes, text adjustment, alignment, etc. when using the annotate argument

Fixed bug that made it impossible to control which channel to highlight when plotting multiple channels and other frames

Added option to add a vector of strings to wave_color, for plotting different channels using different colors.

Fixed bug that made it impossible to control the lower frequency range of spectrograms.

Options added to draw straight lines (vertical, horizontal, or otherwise) on plot components with the draw_lines argument. This replaces the formant_dottedLines argument, but doesn’t otherwise change the look of the default formant plot.
Background coloring can now be added to lines and speckles when any of the *_plotOnSpec options are TRUE. This is done by adding a vector of two strings to the *_color argument, e.g. pitch_color=c('blue','lightblue') for a blue pitch contour on a light blue background. For formant_color, which already allowed a vector of multiple strings, this creates a range of options: If you pass just two strings but are plotting >2 formants, e.g. c('black','white') all formants will be plotted in black on a white background. If you pass N formants + 1 string, the final color will be used as background for all formants. If you pass double the number of formants, the second half will be used for individual background colors.
Option added for both drawing and speckling formants and pitch in a single plot. Before *_plotType had to be either 'draw' or 'speckle', now also allows c('draw','speckle').
