This package provides a programmatic interface to the web service methods provided by Global Biotic Interactions ('GloBI') (<https://www.globalbioticinteractions.org/>). GloBI provides access to spatial-temporal species interaction records from sources all over the world. rglobi provides methods to search species interactions by location, interaction type, and taxonomic name.

This package provides functions for assessing the replication/preservation of a network module's topology across datasets through permutation testing.

This package provides a simple client package for the Amazon Web Services (AWS) Simple Storage Service (S3) REST API.

This package enables you to define a command-line interface by just giving it a description in the specific format.

This package provides functions to identify genomic regions of interests based on segmented copy number data from multiple samples.

This package provide simulation based methods for evaluating the statistical power in differential expression analysis from RNA-seq data.

Dynamic regression for time series using Extreme Gradient Boosting with hyper-parameter tuning via Bayesian Optimization or Random Search.

Collection of functions, data sets and code examples for evaluations of field trials with the objective of equivalence assessment.

Visualizes results of item analysis such as item difficulty, item discrimination, and coefficient alpha for ease of result communication.

Encrypts and decrypts strings using either the Caesar cipher or a pseudorandom number generation (using set.seed()) method.

Variance estimation on indicators of income concentration and poverty using complex sample survey designs. Wrapper around the survey package.

Basic routines used in scientific coding, such as timing routines, vector/array handing functions and I/O support routines.

This package provides a system for the management, assessment, and psychometric analysis of data from educational and psychological tests.
