LLines: Add a spectrum to an existing log-log spectral plot.

In EarthSystemDiagnostics/paleospec: Spectral tools for the ECUS group

Add a spectrum to an existing log-log spectral plot.

Description

This function adds a spectrum to an existing double-logarithmic plot and optionally adds a transparent confidence interval.

Usage

LLines(
  x,
  conf = TRUE,
  bPeriod = FALSE,
  col = "black",
  alpha = 0.3,
  removeFirst = 0,
  removeLast = 0,
  ...
)

Arguments

x	a spectral object resulting from a call to SpecMTM.
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.
col	color for the line plot and the confidence interval.
alpha	transparency level (between 0 and 1) for the confidence interval. Defaults to 0.3.
removeFirst	omit removeFirst values on the low frequency side.
removeLast	omit removeLast values on the high frequency side.
...	further graphical parameters passed to lines.
