In remnrem/luna: Analysis of Sleep Signal Data

LUNA plotting

Description

draws a 'topoplot' using a heatmap color scale

Usage

ltopo.heat(
  c,
  z,
  sz = 1,
  flt = rep(T, length(z)),
  zlab = "",
  mt = "",
  zlim = NULL,
  th = NA,
  th.z = z,
  show.leg = F,
  zeroed = F,
  head = F
)

Arguments

c	vector of channel labels
z	vector of values to plot (same length as c)
sz	integer: size of channel circles plotted (default = 1)
flt	boolean filter of length equal to length(c)
zlab	label for Z-axis
mt	main title label
zlim	set Z range (defaults to observed range)
th	single numeric value threshold for highlighting certain channels (default NULL)
th.z	vector, same length as c and z; channels with th.z \ge th are highlighted
show.leg	boolean: plot a legend (default T)
zeroed	boolean: make Z range symmetric around zero if T (default = F)
head	boolean: draw simple head image (circle, default = F)

Value

plot is generated in the current graphics device; no return value

Examples

## Not run: 
ltopo.heat(psd$CH, psd$PSD, flt = psd$F == 15, sz = 3, zlab = "Power 15 Hz", mt = "Plot 1")

## End(Not run)
