In praatpicture: 'Praat Picture' Style Plots of Acoustic Data

Plot intensity object

Description

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

Usage

intensityplot(
  it,
  start,
  end,
  tfrom0 = TRUE,
  tgbool = FALSE,
  lines = NULL,
  focusTierColor = "black",
  focusTierLineType = "dotted",
  range = NULL,
  color = "black",
  ind = NULL,
  min_max_only = TRUE,
  highlight = NULL,
  axisLabel = "Intensity (dB)",
  drawSize = 1
)

Arguments

it	IntensityTier object loaded using rPraat::it.read
start	Start time (in seconds) of desired plotted area.
end	End time (in seconds) of desired plotted area.
tfrom0	Logical; should time on the x-axis run from 0 or from the original time? Default is TRUE.
tgbool	Logical; should dotted lines be plotted corresponding to locations in a TextGrid? Default is FALSE.
lines	Numeric vector giving locations in seconds of locations from a TextGrid to be plotted with dotted lines. Default is NULL.
focusTierColor	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'.
focusTierLineType	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'.
range	Vector of two integers giving the intensity range to be used for producing intensity plots. Default is NULL, in which case the range is simply the minimum and maximum levels in the curve.
color	String giving the name of the color to be used for plotting intensity. Default is 'black'.
ind	Integer indexing waveform relative to other plot components. Default is NULL.
min_max_only	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.
highlight	Named list giving parameters for differential highlighting of the intensity contour 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) and drawSize (integer), and background (a string specifying a background color).
axisLabel	String giving the name of the label to print along the y-axis when plotting intensity. Default is Intensity (dB).
drawSize	Number indicating the line width of the intensity contour. Default is 1. Controls the lwd argument of graphics::lines.

Value

No return values, called internally by praatpicture and sibling functions.

Examples

# Don't use directly
datapath <- system.file('extdata', package='praatpicture')
soundFile <- paste0(datapath, '/1.wav')
praatpicture(soundFile, frames='intensity')
