Key Derivation Functions for R Based on Scrypt

Functions for working with the scrypt key derivation functions originally described by Colin Percival < https://www.tarsnap.com/scrypt/scrypt.pdf> and in Percival and Josefsson (2016) . Scrypt is a password-based key derivation function created by Colin Percival. The algorithm was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory.

An Event-Based Mechanism for 'Shiny'

An event-Based framework for building 'Shiny' apps. Instead of relying on standard 'Shiny' reactive objects, this package allow to relying on a lighter set of triggers, so that reactive contexts can be invalidated with more control.

Stock Assessment Graphs Database Web Services

R interface to access the web services of the ICES Stock Assessment Graphs database < https://sg.ices.dk>.

Formal Parser and Related Tools for R Markdown Documents

An implementation of a formal grammar and parser for R Markdown documents using the Boost Spirit X3 library. It also includes a collection of high level functions for working with the resulting abstract syntax tree.

Access the 'languagelayer' API

Improve your text analysis with languagelayer < https://languagelayer.com>, a powerful language detection API.

Multidimensional Nuclear Magnetic Resonance Peak Fitting and Analysis

Tools for fitting and analyzing 1D-4D nuclear magnetic resonance spectra with analytical models of peak shapes and peak groups. The package reads spectra in 'NMRPipe' format, builds constrained parameter structures for chemical shifts, line widths, scalar couplings, volumes, and phases, and performs nonlinear least-squares optimization for iterative peak discovery or simultaneous fits across multiple spectra. It also provides methods for visualization, preprocessing, and kinetic analysis of 1D time-series data, including automated phase optimization, solvent suppression, time-domain correction for frequency shifts and line broadening, modeling spectra as linear combinations of two component spectra, and exponential rate fitting.

Run Quality Checks on Data Prior to Submission to ICES

Run quality checks on data sets using the same checks that are conducted on the ICES Data Submission Utility (DATSU) < https://datsu.ices.dk>.

Predict Fish Year-Class Strength from Survey Data

Predict fish year-class strength by calibration regression analysis of multiple recruitment index series.
