IRB is an interactive Ruby command-line tool for REPL (Read Eval Print Loop).
Read and write Matlab MAT files from R. The rmatio package supports reading MAT version 4, MAT version 5 and MAT compressed version 5. The rmatio package can write version 5 MAT files and version 5 files with variable compression.
Rapid, simulation-based exact (restricted) likelihood ratio tests for testing the presence of variance components/nonparametric terms for models fit with nlme::lme(), lme4::lmer(), lmeTest::lmer(), gamm4::gamm4(), mgcv::gamm() and SemiPar::spm().
The Regional Vulnerability Index (RVI), a statistical measure of brain structural abnormality, quantifies an individual's similarity to the expected pattern (effect size) of deficits in schizophrenia (Kochunov P, Fan F, Ryan MC, et al. (2020) <doi:10.1002/hbm.25045>).
Random univariate and multivariate finite mixture model generation, estimation, clustering, latent class analysis and classification. Variables can be continuous, discrete, independent or dependent and may follow normal, lognormal, Weibull, gamma, Gumbel, binomial, Poisson, Dirac, uniform or circular von Mises parametric families.
This package provides a programmatic client for the eBird database (<https://ebird.org/home>), including functions for searching for bird observations by geographic location (latitude, longitude), eBird hotspots, location identifiers, by notable sightings, by region, and by taxonomic name.
R6 class interface for handling relational database connections using DBI package as backend. The class allows handling of connections to e.g. PostgreSQL, MariaDB and SQLite. The purpose is having an intuitive object allowing straightforward handling of SQL databases.
This package provides a series of functions to call AD Model Builder (i.e., compile and run models) from within R, read the results back into R as admb objects, and provide standard accessors (i.e. coef(), vcov(), etc.).
Download large sections of GenBank <https://www.ncbi.nlm.nih.gov/genbank/> and generate a local SQL-based database. A user can then query this database using restez functions or through rentrez <https://CRAN.R-project.org/package=rentrez> wrappers.
This package provides a method for fitting the entire regularization path of the reluctant generalized additive model (RGAM) for linear regression, logistic, Poisson and Cox regression models. See Tay, J. K., and Tibshirani, R., (2019) <arXiv:1912.01808> for details.
This package provides a DBI interface to MySQL / MariaDB. The RMySQL package contains an old implementation based on legacy code from S-PLUS which is being phased out. A modern MySQL client based on Rcpp is available from the RMariaDB package.
This package provides infrastructure to accurately measure and compare the execution time of R expressions.
Fits a pseudo Cox proprotional hazards model when survival times are missing for control groups.
Nonparametric change point estimation for survival data based on p-values of exact binomial tests.
Compute degree days from daily min and max temperatures for modeling plant and insect development.
Geometric objects defined in geozoo can be simulated or displayed in the R package tourr'.
This package provides methods for calculating gradient surface metrics for continuous analysis of landscape features.
Efficient algorithms for fitting regularization paths for linear or logistic regression models penalized by LEP.
The geom_rain() function adds different geoms together using ggplot2 to create raincloud plots.
Display hexagonally binned scatterplots for multi-class data, using coloured triangles to show class proportions.
This package provides a bunch of functions to deal with circular data under order restrictions.
Some simple objects and functions to do statistics using linear models and a Bayesian framework.
Exploratory model analysis with <http://ggobi.org>. Fit and graphical explore ensembles of linear models.
Tailoring the optimal biomarker(s) for disease screening or diagnosis based on subjects individual characteristics.
