Named Entity Recognition in Texts using 'NameTag'
Wraps the 'nametag' library < https://github.com/ufal/nametag>, allowing users to find and extract entities (names, persons, locations, addresses, ...) in raw text and build your own entity recognition models. Based on a maximum entropy Markov model which is described in Strakova J., Straka M. and Hajic J. (2013) < https://ufal.mff.cuni.cz/~straka/papers/2013-tsd_ner.pdf>.
Estimate and Test Exponential vs. Pareto Distributions
The programs were developed for estimation of parameters and testing exponential versus Pareto distribution during our work on hydrologic extremes. See Kozubowski, T.J., A.K. Panorska, F. Qeadan, and A. Gershunov (2007)
Automatic Data Processing and Visualization for FRAP
Automatically process Fluorescence Recovery After Photobleaching (FRAP) data and generate consistent, publishable figures. Note: this package does not replace 'ImageJ' (or its equivalence) in raw image quantification. Some references about the methods: Sprague, Brian L. (2004)
Working Examples for Reproducible Research Documents
Templates, guides, and scripts for writing documents in 'LaTeX' and 'R markdown' to produce guides, slides, and reports. Special care is taken to illustrate use of templates and customization opportunities. Challenges and opportunities of 'HTML' output from 'R markdown' receive special attention. Includes several vignettes to assist new users of literate programming.
Wrangle Phylogenetic Distance Matrices and Other Utilities
Harriet was Charles Darwin's pet tortoise (possibly). 'harrietr' implements some function to manipulate distance matrices and phylogenetic trees to make it easier to plot with 'ggplot2' and to manipulate using 'tidyverse' tools.
Kalman Filter
'Rcpp' implementation of the multivariate Kalman filter for state space models that can handle missing values and exogenous data in the observation and state equations. There is also a function to handle time varying parameters.

Shared Tools for Tracking Data
A collection of commonly used tools for animal movement and other tracking
data. Variously distance, angle, bearing, distance-to, bearing-to and speed are
provided for geographic data that can be used directly or within 'tidyverse'
syntax. Distances and bearings are calculated using modern geodesic methods as
provided by Charles F. F. Karney (2013)
Clustering of Functional Data via Mixtures of t-Distributions
Extension of 'funHDDC' Schmutz et al. (2018)
Co-Clustering of Ordinal Data via Latent Continuous Random Variables
It implements functions for simulation and estimation of the ordinal latent block model (OLBM), as described in Corneli, Bouveyron and Latouche (2019).
A Tool for Sensitivity Analysis in Structural Equation Modeling
Perform sensitivity analysis in structural equation modeling using
meta-heuristic optimization methods (e.g., ant colony optimization and others).
