melodyplot: Plotting a melody

Description

Plot a observed melody and (optional) an expected melody, as well as corresponding energy values (corresponding to the loudness of the sound).

Usage

melodyplot(object, observed, expected = NULL, bars = NULL, 
    main = NULL, xlab = NULL, ylab = "note", xlim = NULL, ylim = NULL, 
    observedcol = "red", expectedcol = "grey", gridcol = "grey",
    lwd = 2, las = 1, cex.axis = 0.9, mar = c(5, 4, 4, 4) + 0.1,
    notenames = NULL, silence = "silence", plotenergy = TRUE, ...,
    axispar = list(ax1 = list(side=1),
                   ax2 = list(side=2), 
                   ax4 = list(side=4)),
    boxpar = list(), 
    energylabel = list(text="energy", side=4, line=2.5, at=rg.s-0.25, las=3),
    energypar = list(), 
    expectedpar = list(),
    gridpar = list(col = gridcol), 
    observedpar = list(col = observedcol, lwd = 2))

Arguments

object
An object of class Wspec.
observed
Observed notes, probably as a result from noteFromFF (or a smoothed version). This should correspond to the Wspec object.
expected
Expected notes (optional; in order to compare results).
bars
Number of bars to be plotted (a virtual static segmentation takes place). If NULL (default), time rather than bars are used.
main
Main title of the plot.
xlab, ylab
Annotation of x/y-axes.
xlim, ylim
Range of x/y-axis.
observedcol
Colour for the observed melody.
expectedcol
Colour for the expected melody.
gridcol
Colour of the grid.
lwd
Line width, see par for details.
las
Orientation of axis labels, see par for details.
cex.axis
Size of tick mark labels, see par for details.
mar
Margins of the plot, see par for details.
notenames
Optionally specify other notenames (character) for the y axis.
silence
Character string for label of the silence (default) axis.
plotenergy
Logical (default: TRUE), whether to plot energy values in the bottom part of the plot.
...
Additional graphical parameters to be passed to underlying plot function.
axispar
A named list of three other lists (ax1,ax2, and ax4) containing parameters passed to the corresponding axis calls for the three axis time (ax1), no
boxpar
A list of parameters to be passed to the box generating functions.
energylabel
A list of parameters to be passed to the energy-label generating mtext call.
energypar
A list of parameters to be passed to the lines function that draws the energy curve.
expectedpar
A list of parameters to be passed to the rect function that draws the rectangles for expected values.
gridpar
A list of parameters to be passed to the abline function that draws the grid lines.
observedpar
A list of parameters to be passed to the lines function that draws the observed values.
