LUNA plotting

Description

draws a 'topoplot' using a red-blue color scale

Usage

ltopo.rb(
  c,
  z,
  flt = rep(T, length(z)),
  sz = 1,
  zlab = "",
  mt = "",
  zlim = NULL,
  th = NULL,
  th.z = z,
  show.leg = F,
  zeroed = T,
  head = F,
  col = (grDevices::colorRampPalette(c("blue", "white", "red")))(101),
  ring.lwd = 1
)

Arguments

c	vector of channel labels
z	vector of values to plot (same length as c)
flt	boolean filter of length equal to length(c)
sz	integer: size of channel circles plotted (default = 1)
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)
col	101-valued palette, defaults to grDevices::colorRampPalette(c("blue", "white", "red"))(101)
ring.lwd	width of rings around highlighted channels (defaults to 1)#'

Value

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

Note

ltopo.rb(...) is the same as ltopo.heat(...) with zeroed = T and a different color scheme (blue as negative, red as positive, white as 0)
