LUNA plotting

Description

draw a series of X-Y scatter/line plots, one-per-channel arranged as a topoplot

Usage

ltopo.xy(
  c,
  x,
  y,
  z = NA,
  zlim = NA,
  f = rep(T, length(x)),
  y.symm = F,
  sz = 0.08,
  col = "black",
  lwd = 0.5,
  xline = numeric(),
  yline = numeric(),
  pch = NA,
  cex = 1,
  ylim = NULL,
  xlab = "Frequency (Hz)",
  ylab = "log(power)",
  mt = ""
)

Arguments

c	character vector of channel labels
x	nuremic vector of X-axis values
y	numeric vector of Y-axis values
z	optional numeric vector of Z-axis values (default NA)
zlim	optional range for Z
f	optional boolean vector of length(x), filter in/out each observation
y.symm	boolean, make Y-axis symmetric around 0 (default = F)
sz	optional numeric value: size of points (default 0.08)
col	optional color, default 'black'
lwd	optional numeric value for line width (default to 0.5)
xline	optional vector of X values to plot vertical lines
yline	optional vector of Y values to plot horizontal lines
pch	optional point symbol (default NA)
cex	optional point size (default 1)
ylim	optional Y axis limit
xlab	X axis label (default = Frequency Hz))
ylab	Y axis label (default = log(power))
mt	main title (default, "")

Value

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

Note

If pch is non-NULL, then z can be a vector of values (length(x)) and col can be a 100-element palette: in this case, the color of each point is scaled by the percentile of z; if pch is missing, this function draws a X-Y line plots, which must be a single color (i.e. no z values are allowed)

Examples

## Not run: 
ltopo.xy(c = hj$CH, x = hj$E, y = log(hj$H1), xlab = "Epoch", ylab = "H1",
    pch=20, col=rbpal, cex = 0.2)

## End(Not run)
