LPlot: Plot spectral object

In EarthSystemDiagnostics/proxysnr: Separate Signal and Noise in Climate Proxy Records

Plot spectral object

Description

Plot a spectral object on a double-logarithmic scale, optionally adding a transparent confidence interval.

Usage

LPlot(
  x,
  type = "l",
  inverse = FALSE,
  conf = TRUE,
  axes = TRUE,
  col = "black",
  alpha = 0.2,
  removeFirst = 0,
  removeLast = 0,
  xlab = ifelse(inverse, "period", "f"),
  ylab = "PSD",
  xlim = NULL,
  ylim = NULL,
  ...
)

Arguments

x	a spectral object.
type	1-character string giving the type of plot desired: default type "l" makes a line plot, while type "n" produces only the plot frame; see also plot.default.
inverse	if TRUE the x-axis is displayed in units of period (inverse frequency), increasing to the left; defaults to FALSE.
conf	if TRUE (the default) add a transparent confidence interval (has no effect if x contains no confidence limits).
axes	if FALSE the plotting of the x and y axes is suppressed; defaults to TRUE.
col	color for the line plot and the confidence interval.
alpha	transparency level (between 0 and 1) for the confidence interval; defaults to 0.2.
removeFirst	omit removeFirst values on the low frequency side.
removeLast	omit removeLast values on the high frequency side.
xlab	character string for labelling the x-axis.
ylab	character string for labelling the y-axis.
xlim	range of x-axis values; if NULL (the default) it is calculated internally and automatically reversed if inverse = TRUE.
ylim	range of y-axis values; if NULL (the default) it is calculated internally.
...	further graphical parameters passed to plot.
