Multiplex Network Analysis
Interactions between different biological entities are crucial for the function of biological systems.
In such networks, nodes represent biological elements, such as genes, proteins and microbes, and their interactions can be defined by edges, which can be either binary or weighted.
The dysregulation of these networks can be associated with different clinical conditions such as diseases and response to treatments.
However, such variations often occur locally and do not concern the whole network.
To capture local variations of such networks, we propose multiplex network differential analysis (MNDA).
MNDA allows to quantify the variations in the local neighborhood of each node (e.g. gene) between the two given clinical states, and to test for statistical significance of such variation.

NETwork COMparison Inference
Infer system functioning with empirical NETwork COMparisons. These methods are part of a growing paradigm in network science that uses relative comparisons of networks to infer mechanistic classifications and predict systemic interventions. They have been developed and applied in Langendorf and Burgess (2021)
Distance Measures for Networks
Network is a prevalent form of data structure in many fields. As an object of analysis, many distance or metric measures have been proposed to define the concept of similarity between two networks. We provide a number of distance measures for networks. See Jurman et al (2011)
Mobility Network Analysis
Implements the method to analyse weighted mobility networks or distribution networks as outlined in:
Block, P., Stadtfeld, C., & Robins, G. (2022)
Road Network Projection
Project road network development based on an existing road
network, target locations to be connected by roads and a cost surface. Road
projection methods include minimum spanning tree with least cost path
(Kruskal's algorithm (1956)
Network of Differential Equations
Simulates a network of ordinary differential equations of order
two. The package provides an easy interface to construct networks. In addition
you are able to define different external triggers to manipulate the trajectory.
The method is described by Surmann, Ligges, and Weihs (2014)
Examples of Neural Networks
Implementations of several basic neural network concepts in R, as based on posts on \url{ http://qua.st/}.
Neural Network Numerai
Interactively train neural networks on Numerai, < https://numer.ai/>, data. Generate tournament predictions and write them to a CSV.
Analyzing Ecological Networks
A collection of advanced tools, methods and models specifically designed for analyzing different types of ecological networks - especially antagonistic (food webs, host-parasite), mutualistic (plant-pollinator, plant-fungus, etc) and competitive networks, as well as their variability in time and space. Statistical models are developed to describe and understand the mechanisms that determine species interactions, and to decipher the organization of these ecological networks (Ohlmann et al. (2019)
Statistically Validated Networks
Determines networks of significant synchronization between the discrete states of nodes; see Tumminello et al
