A Toolkit for PDF Files (staplr)
Provides function to manipulate PDF files: merge multiple PDF files into one; Splits a single input PDF document into individual pages; remove selected pages from a file; rename multiple files in a directory.

Beautiful Graphical Representation of Multiplication Tables on a Modular Circle (rusk)
By placing on a circle 10 points numbered from 1 to 10, and connecting them by a straight line to the point corresponding to its multiplication by 2. (1 must be connected to 1 * 2 = 2, point 2 must be set to 2 * 2 = 4, point 3 to 3 * 2 = 6 and so on). You will obtain an amazing geometric figure that complicates and beautifies itself by varying the number of points and the multiplication table you use.

Kernel Density Estimation with Parametric Starts and Asymmetric Kernels (kdensity)
Handles univariate non-parametric density estimation with parametric starts and asymmetric kernels in a simple and flexible way. Kernel density estimation with parametric starts involves fitting a parametric density to the data before making a correction with kernel density estimation, see Hjort & Glad (1995) <doi:10.1214/aos/1176324627>. Asymmetric kernels make kernel density estimation more efficient on bounded intervals such as (0, 1) and the positive half-line. Supported asymmetric kernels are the gamma kernel of Chen (2000) <doi:10.1023/A:1004165218295>, the beta kernel of Chen (1999) <doi:10.1016/S0167-9473(99)00010-9>, and the copula kernel of Jones & Henderson (2007) <doi:10.1093/biomet/asm068>. User-supplied kernels, parametric starts, and bandwidths are supported.

An HR Analytics Toolkit (hR)
Manipulate and visualize people data in meaningful and common ways. This package is meant for Human Resources analytics (often referred to as talent analytics or people analytics).

Projection Predictive Feature Selection (projpred)
Performs projection predictive feature selection for generalized linear models (see, e.g., Piironen and Vehtari, 2017, <doi:10.1007/s11222-016-9649-y>). The package is compatible with ‘rstanarm’ package, but other reference models can also be used. See the package vignette for more information and examples.
