extremes.interactive: Extracting extreme events in the 'climex' app

In theGreatWhiteShark/climexUI: Shiny-based User Interface to Analyse Large Amounts of Station Data Using The Climex Package

Description

Function to extract the extreme event from a time series.

Usage

extremes.interactive(x.xts, buttonMinMax, radioEvdStatistics,
  sliderBlockLength, sliderThreshold, checkboxDecluster)

Arguments

x.xts	Time series of class xts which has to be cleaned.
buttonMinMax	Character (radio) input determining whether the GEV/GP distribution shall be fitted to the smallest or biggest values. Choices: c( "Max", "Min ), default = "Max".
radioEvdStatistics	Character (radio) input determining whether the GEV or GP distribution shall be fitted to the data. Choices: c( "GEV", "GP" ), default = "GEV".
sliderBlockLength	Numerical (slider) input determining the block length used in the GEV flavor of extreme value theory. On default it is set to one year.
sliderThreshold	Numerical (slider) input determining the threshold used within the GP fit and the extraction of the extreme events. Boundaries: minimal and maximal value of the deseasonalized time series (rounded). Default: 0.8* the upper end point.
checkboxDecluster	Logical (checkbox) input determining whether to remove all clusters in a time series and to replace them by their maximal value. This box will be only available if radioEvdStatistics equals "GP" and else will be NULL.

Details

If radioEvdStatistics is set to "GEV", the time series will be block. If it's on the other hand set to "GP", all values above a threshold sliderThreshold will be extracted.

Value

Time series of class xts.
