Plot Lomb-Scargle Periodogram
Plots the normalised power as a function of frequency (or period, depending on type in function lsp).
## S3 method for class 'lsp'
plot(x, type = "l", main = "Lomb-Scargle Periodogram", xlab = NULL,
ylab = "normalised power", level = TRUE, log = NULL, ...)x |
Object of class lsp as returned from function lsp. |
type |
Character indicating the type of plotting. Any of the types as in plot.default. |
main |
Character. Main title of the periodogram plot. Defaults to “Lomb-Sargle Periodogram”. |
xlab |
Character. X-axis label of the periodogram plot. |
ylab |
Character. Y-axis label of the periodogram plot. |
level |
Logical. If TRUE, the siginificance level is displayed as a dashed line. |
log |
By default, periodgrams of type=“period” are shown with a log x-axis. If desired otherwise, use log=“..” to define log-axis as in plot.default |

Additional graphics parameters |
Usually, this function is only called by function lsp. It maybe called by the user for some control of the ouput. For better control, plot results from lsp ($scanned, $power) as desired.
Invisibly returns the object of class lsp it is called with.
