In one-dimensional \(^1\)H NMR spectroscopy, particularly biomolecular NMR, it is frequently necessary to align spectra before chemometric or metabolomics analysis. Poor alignment arises largely from pH and ionic strength induced shifts in aqueous samples. There are a number of published alignment algorithms for the one-dimensional case. In this series of ...

A flexible framework for probabilistic forecasting of circular data is introduced, using distributional regression trees and random forests based on the von Mises distribution. Citation Lang MN, Schlosser L, Hothorn T, Mayr GJ,...

Continuing our effort of applying the principles of reactivity to the UI part of a ShinyApp, this blog introduces two ways of conditionally rendering UI-elements in your app. Both presented solutions accomplish the same goal, once from the server part and once from the UI part of your application. Der ...
