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

Features

An interactive web app

- You can perform extreme value analysis on a large number of different time series - You can calculate arbitrary return levels for all stations and display the results comprehensively on a map

- You have full control over all steps involved in the extreme value analysis via an intuitive GUI in a persistent way (changes will be applied to the analysis of all following time series) - Both the Generalized Extreme Value (GEV) and the Generalized Pareto (GP) approach are supported - You can exclude single points or whole parts of a time series with the entire analysis being recalculated immediately - The fitting is done using a nonlinear constrained maximum likelihood procedure based on the augmented Lagrangian method. Using this approach none of your fits will produce numerical artifacts. See the climex package for details

Try it!

Installation

Since the shiny-based web app uses rather new features of the R programming language, you have to have at least R-3.3.0 or newer (you can check your version by running R --version in the terminal). If you don't fulfill this condition yet, be sure to get the binary or source of an appropriate R version via CRAN.

To install this package, you can use the install_gitlab() function from the devtools package.

Just open a R shell on your computer and type in the following commands

## Installing the devtools package (in case your haven't done it yet).
install.packages( "devtools" )

## Installing the climex package from Github.
devtools::install_gitlab( "theGreatWhiteShark/climexUI" )

Server-side installation of the Climex web application

You want to run your own version of the Climex web application on one of your servers so others can access it too? Then check out this configuration guide.

Usage

A thorough introduction into the web app is provided via this vignette.
