LPlot: Log-log spectral plot

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

Description

This function plots a spectrum on a double-logarithmic scale and optionally adds a transparent confidence interval.

Usage

LPlot(
  x,
  conf = TRUE,
  bPeriod = FALSE,
  bNoPlot = FALSE,
  axes = TRUE,
  col = "black",
  alpha = 0.2,
  removeFirst = 0,
  removeLast = 0,
  xlab = "f",
  ylab = "PSD",
  xlim = NULL,
  ylim = NULL,
  ...
)

Arguments

x	an object of class "spec".
conf	if TRUE (the default) add a transparent confidence interval (suppressed if x contains no error limits).
bPeriod	if TRUE the x-axis is displayed in units of period (inverse frequency), increasing to the left. Defaults to FALSE.
bNoPlot	if TRUE only produce the plot frame (type = "n" behaviour of function plot). Defaults to FALSE.
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 for bPeriod = TRUE.
ylim	range of y-axis values; if NULL (the default) it is calculated internally.
...	further graphical parameters passed to plot.
