September was another relatively slow month for new package activity on CRAN: “only” 126 new packages by my count. My Top 40 list is heavy on what I characterize as “utilities”: packages that either extend R in some fashion or make it easier to do things in R. This month, the packages I selected fall into eight categories: Data, Finance, Machine Learning, Science, Statistics, Time Series, Utilities and Visualization.

portsort v0.1.0: Provides functions to sort assets into portfolios for up to three factors via a conditional or unconditional sorting procedure. There is an Introduction.

Machine Learning

crfsuite v0.1.1: Wraps the CRFsuite library allowing users to fit a conditional random field model. The focus is Natural Language Processing, and there are models for named entity recognition, text chunking, part of speech tagging, intent recognition, and classification. The vignette shows how to use the package.

ELMSO v1.0.0: Implements the algorithm described in Paulson, Luo, and James (2018); see here for a full-text version of the paper. The algorithm allocates budget across a set of online advertising opportunities.

newsmap v0.6: Implements a semi-supervised model for geographical document classification ([Watanabe (2018)])(doi:10.108021670811.2017.1293487) with seed dictionaries in English, German, Spanish, Japanese, and Russian. See the README for an example.

splinetree v0.1.0: Provides functions to build regression trees and random forests for longitudinal or functional data using a spline projection method. Implements and extends the work of Yu and Lambert (1999). There is an Introduction and vignettes on trees and forests.

stylest v0.1.0: Provides functions to estimate the distinctiveness in speakers’ (authors’) style. Fits models that can be used for predicting speakers of new texts. See Spirling et al (2018) for the details and the vignette for an example on how to use the package.


conStruct v1.0.0: Provides a method for modeling genetic data as a combination of discrete layers, within each of which relatedness may decay continuously with geographic distance. There are vignettes for formatting data, model construction, and on running and visualizing consStruct analyses.

episcan v0.0.1: Provides some efficient mechanisms to scan epistasis in genome-wide interaction studies (GWIS), and supports both case-control status (binary outcome) and quantitative phenotype (continuous outcome) studies. See Kam-Thong and Cxamara et al. (2011), Kam-Thong and Pütz et al. (2011), and the vignette.


ahpsurvey v0.2.2: Implements the Analytic Hierarchy Process, a versatile multi-criteria decision-making tool introduced by Saaty (1987) that allows decision-makers to weigh attributes and evaluate alternatives presented to them. The vignette provides examples.

empirical v0.1.0: Implements empirical univariate probability density functions (continuous functions) and empirical cumulative distribution functions (step functions or continuous). The vignette provides examples.

basisMCMCplots v0.1.0: Provides functions for examining posterior MCMC samples from a single and multiple chains that interface with the NIMBLE software package. See de Valpine et al. (2017).

MetaStan v0.0.1: Provides functions to perform Bayesian meta-analysis using Stan. Includes binomial-normal hierarchical models and option to use weakly informative priors for the heterogeneity parameter and the treatment effect parameter, which are described in Guenhan, Roever, and Friede (2018). The vignette contains an example.

Opt4PL v0.1.1: Provides functions to obtain and evaluate various optimal designs for the 3-, 4-, and 5-parameter logistic models. The optimal designs are obtained based on the numerical algorithm in Hyun, Wong, Yang (2018).

rmatalog v1.0.0: Implements the metalog distribution, a modern, highly flexible, data-driven distribution. See Keelin (2016). The vignette provides an example.

rwavelet v0.1.0: Provides functions to perform wavelet analysis (orthogonal and translation invariant transforms) with applications to data compression or denoising. Most of the code is a port of the MATLAB Wavelab toolbox written by Donoho, Maleki and Shahram. The vignette provides examples.

samplingBigData v1.0.0: Provides methods for sampling large data sets, including spatially balanced sampling in multi-dimensional spaces with any prescribed inclusion probabilities. Written in C, it uses efficient data structures such as k-d trees that scale to several million rows on a modern desktop computer.

survivalAnalysis v0.1.0: Implements a high-level interface to perform survival analysis, including Kaplan-Meier analysis and log-rank tests and Cox regression. There are vignettes for univariate and multivariate survival analyses.

ungroup v1.1.0: Provides functions to implement a penalized composite link model for efficient estimation of smooth distributions from coarsely binned data. For a detailed description of the method and applications, see Rizzi et al. (2015). The vignette provides examples.
