Plot an observed melody and (optional) an expected melody,
as well as corresponding energy values (corresponding to the loudness of the sound)
within a quantization grid.
Either a vector of observed notes resulting from some quantization,
or a list with components notes (observed notes) and energy (corresponding energy values),
e.g. the result from a call to quantize.
energy
A vector of energy values with same quantization as observed
(overwrites any given energy values if observed is a list).
expected
Expected notes (optional; in order to compare results).
bars
Number of bars to be plotted (e.g. corresponding to quantize arguments).
barseg
Number of segments (minimal length notes) in each bar.
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 notes.
expectedcol
Colour for the expected notes.
gridcol
Colour of the inner-bar 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 indicating whether to plot energy values in the bottom part of the plot (default is TRUE)
if energy values are specified, and FALSE otherwise.
...
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), notes (ax2), and energy (ax4).
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 points function
that draws the energy values.
expectedpar
A list of parameters to be passed to the rect
function that draws the rectangles for expected values.
gridpar
A named list of two other lists (gridbar and gridinner)
containing parameters passed to the abline functions that draw the grid lines
(for bar separators and inner bar (note) separators).
observedpar
A list of parameters to be passed to the lines
function that draws the observed values.
