plot.lomb: plot method for Lomb-Scargle periodograms

In spectral: Common Methods of Spectral Data Analysis

Description

This method plots a standard Lomb-Scargle periodogram, which contains the normalized power spectra PSD and the corresponding false alarm probability p. For more details refer to Zechmeister et al. (2009).

Usage

## S3 method for class 'lomb'
plot(
  x,
  FAPcol = 1,
  FAPlwd = 1,
  FAPlty = "dashed",
  FAPlim = c(1, 0.001),
  FAPlab = "FAP",
  legend.pos = "topleft",
  legend.cex = 1,
  legend.on = T,
  legend.text = c("Spectrum", "False Alarm Probability"),
  legend.lwd = NULL,
  legend.lty = NULL,
  legend.col = NULL,
  xlab = "Frequency",
  ylab = "Normalized PSD",
  main = "",
  ...
)

Arguments

x	object of class lomb
FAPcol	color of the FAP line
FAPlwd	line width of the FAP line
FAPlty	line type for the FAP graph
FAPlim	limits to the FAP
FAPlab	label of the right vertical axis
legend.pos	position of the legend
legend.cex	cex value for the legend
legend.on	logical, wheater to draw a legend or not
legend.text	legend text
legend.lwd	line width
legend.lty	line type
legend.col	color vector of the legend elements
xlab	a label for the x axis, defaults to a description of x.
ylab	a label for the y axis, defaults to a description of y.
main	setting the title of the plot
...	further parameters to the plot function

Details

The plot.lomb function is a wrapper function for R's standard scatter plot To switch off certain properties, simply overwrite the parameter. For example log = "" will reset the plot axis back to non-log scale.
