Objective General Index (OGI)
Consider a data matrix of n individuals with p variates. The objective general index (OGI) is a general index that combines the p variates into a univariate index in order to rank the n individuals. The OGI is always positively correlated with each of the variates. More details can be found in Sei (2016) <doi:10.1016/j.jmva.2016.02.005>.

Generalized Linear Latent Variable Models (gllvm)
Generalized linear latent variable model (gllvm) for analyzing multivariate data. Estimation is performed using either Laplace approximation or variational approximation method implemented via TMB (Kristensen et al., (2016), <doi:10.18637/jss.v070.i05>). Details for gllvm, see Hui et al. (2015) <doi:10.1111/2041-210X.12236> and (2017) <doi:10.1080/10618600.2016.1164708> and Niku et al. (2017) <doi:10.1007/s13253-017-0304-7>.

Read, Inspect, and Manipulate Color Swatch Files (swatches)
There are numerous places to create and download color palettes. These are usually shared in ‘Adobe’ swatch file formats of some kind. There is also often the need to use standard palettes developed within an organization to ensure that aesthetics are carried over into all projects and output. Now there is a way to read these swatch files in R and avoid transcribing or converting color values by hand or or with other programs. This package provides functions to read and inspect ‘Adobe Color’ (‘ACO’), ‘Adobe Swatch Exchange’ (‘ASE’), ‘GIMP Palette’ (‘GPL’), ‘OpenOffice’ palette (‘SOC’) files and ‘KDE Palette’ (‘colors’) files. Detailed descriptions of ‘Adobe Color’ and ‘Swatch Exchange’ file formats as well as other swatch file formats can be found at <http://…/fileformats.php>.

Label Attributes for Atomic Vectors (labelVector)
Labels are a common construct in statistical software providing a human readable description of a variable. While variable names are succinct, quick to type, and follow a language’s naming conventions, labels may be more illustrative and may use plain text and spaces. R does not provide native support for labels. Some packages, however, have made this feature available. Most notably, the ‘Hmisc’ package provides labelling methods for a number of different object. Due to design decisions, these methods are not all exported, and so are unavailable for use in package development. The ‘labelVector’ package supports labels for atomic vectors in a light-weight design that is suitable for use in other packages.

Implementation of the 3D Alpha-Shape for the Reconstruction of 3D Sets from a Point Cloud (alphashape3d)
Implementation in R of the alpha-shape of a finite set of points in the three-dimensional space. The alpha-shape generalizes the convex hull and allows to recover the shape of non-convex and even non-connected sets in 3D, given a random sample of points taken into it. Besides the computation of the alpha-shape, this package provides users with functions to compute the volume of the alpha-shape, identify the connected components and facilitate the three-dimensional graphical visualization of the estimated set.

Power and Sample Size Calculation for the Cochran-Mantel-Haenszel Test (samplesizeCMH)
Calculates the power and sample size for Cochran-Mantel-Haenszel tests. There are also several helper functions for working with probability, odds, relative risk, and odds ratio values.
