filled.contour.mod: Modified filled.contour

In soundgen: Sound Synthesis and Acoustic Analysis

Modified filled.contour

Description

Internal soundgen function

Usage

filled.contour.mod(
  x = seq(0, 1, len = nrow(z)),
  y = seq(0, 1, len = ncol(z)),
  z,
  xlim = range(x, finite = TRUE),
  ylim = range(y, finite = TRUE),
  zlim = range(z, finite = TRUE),
  levels = pretty(zlim, nlevels),
  nlevels = 30,
  color.palette = function(n) grDevices::hcl.colors(n, "YlOrRd", rev = TRUE),
  col = color.palette(length(levels) - 1),
  legend = FALSE,
  asp = NA,
  xaxs = "i",
  yaxs = "i",
  las = 1,
  log = "",
  yScale = c("orig", "bark", "mel", "ERB")[1],
  axisX = TRUE,
  axisY = TRUE,
  maxPoints = 5e+05,
  ...
)

Arguments

x, y	locations of grid lines (NB: x = time, y = frequency in kHz, not Hz!)
z	numeric matrix of values to plot
xlim, ylim, zlim	limits for the plot
levels	levels for partitioning z
nlevels	numbers of levels for partitioning z
color.palette	color palette function
col	list of colors instead of color.palette
asp, xaxs, yaxs, ...	graphical parameters passed to plot.window() and axis()
log	log = 'y' log-transforms the y axis
axisX, axisY	plot the axis or not (logical)

Details

A bare-bones version of filled.contour that does not plot a legend and accepts some additional graphical parameters like tick marks.

Examples

data(sheep, package = 'seewave')
spec = spectrogram(sheep, from = 0.3, to = 0.6, plot = FALSE)
soundgen:::filled.contour.mod(z = t(spec))
