Software R package provides R-interface to the NIfTI reference implementation the niftilib C-library.
Software R package for measurement theory, meta-analysis, reliability, item analysis, inter-rater reliability, classical utility, and correlation
Software R package implements S3 class for storing and formatting time-of-day values, based on the 'difftime' class.
Software R package to create Q-Q and manhattan plots for GWAS data from PLINK output files.
Software R package provides base S4 class for comparative methods, incorporating one or more trees and trait data. Used for phylogenetic analysis.
Software R package provides access to phyloinformatic data in 'NeXML' format.
Software R package provides interface to Nexus Class Library which allows parsing of NEXUS, Newick and other phylogenetic tree file formats. Provides elements of file that can be used to build phylogenetic objects such as ape's 'phylo' or phylobase's 'phylo4(d)'.
Software R package useful in analyzing data from psychophysical experiments.Includes functions for calculating d' from several different experimental designs, links for m-alternative forced-choice data to be used with binomial family in glm and self-Start functions for estimating gamma values for CRT screen calibrations.
Software R package for recursive partitioning based on psychometric models, employing general MOB algorithm to obtain Bradley-Terry trees, Rasch trees, rating scale and partial credit trees, and MPT trees, trees for 1PL, 2PL, 3PL and 4PL models and generalized partial credit models.
Software R package provides functions for principal component analysis by projection pursuit.
Software R tools for visualizing, smoothing and comparing receiver operating characteristic. Partial area under curve AUC can be compared with statistical tests based on U-statistics or bootstrap. Confidence intervals can be computed for (p)AUC or ROC curves.
Software R package for parallel estimation of mutual information based on entropy estimates from k-nearest neighbors distances and algorithms for reconstruction of gene regulatory networks.
Software R package provides framework to perform Non-negative Matrix Factorization.Used for nonnegative matrix factorization.Implements set of already published algorithms and seeding methods, and provides framework to test, develop and plug new/custom algorithms. Most of the built-in algorithms have been optimized in C++, and the main interface function provides an easy way of performing parallel computations on multicore machines.
Software R package to compute optimal cutpoints for diagnostic tests or continuous markers.Used for selecting optimal cutoffs, analysis and diagnostic test accuracy measures.
Software R package for creating iterators, many patterned after functions in the Python itertools module, and others patterned after functions in the 'snow' package.
Software R package for clinical trial simulations based on Clinical Scenario Evaluation approach. The package supports broad class of data models, analysis strategies and commonly used evaluation criteria.
Software R package contains methods for detection of clusters in hierarchical clustering dendrograms.
Software R package for handling genetic data. Includes classes to represent genotypes and haplotypes at single markers up to multiple markers on multiple chromosomes. Function include allele frequencies, flagging homo/heterozygotes, flagging carriers of certain alleles, estimating and testing for Hardy-Weinberg disequilibrium, estimating and testing for linkage disequilibrium.
Software R package as implementation of LexRank algorithm. Used for computing sentence importance based on concept of eigenvector centrality in graph representation of sentences.
Software R package for displaying and analysing univariate time series forecasts including exponential smoothing via state space models and automatic ARIMA modelling.
