'NoSQL' Database Connector
Simplified JSON document database access and manipulation, providing a common API across supported 'NoSQL' databases 'Elasticsearch', 'CouchDB', 'MongoDB' as well as 'SQLite/JSON1', 'PostgreSQL', and 'DuckDB'.
Perform Power Analysis for the RI-CLPM and STARTS Model
Perform user-friendly power analyses for the random
intercept cross-lagged panel model (RI-CLPM) and the bivariate stable trait
autoregressive trait state (STARTS) model. The strategy as proposed by
Mulder (2023)
Utilities for Graphical Rendering and Fonts Management
Tools are provided to compute metrics of formatted strings and to check the availability of a font. Another set of functions is provided to support the collection of fonts from 'Google Fonts' in a cache. Their use is simple within 'R Markdown' documents and 'shiny' applications but also with graphic productions generated with the 'ggiraph', 'ragg' and 'svglite' packages or with tabular productions from the 'flextable' package.
R Inputs/Outputs for Tractography
An input-output interface for reading in and writing out common VTK formats that store tractography data. This data comes in the form of 3D polygons with possibly attributes at each point. These are obtained via tracking algorithms from diffusion MRI and are a non-invasive way of studying brain structural connectivity.
Fast Polygon to Raster Conversion
Provides a drop-in replacement for rasterize() from the 'raster'
package that takes polygon vector or data frame objects, and is much faster.
There is support for the main options provided by the rasterize() function,
including setting the field used and background value, and options for
aggregating multi-layer rasters. Uses the scan line algorithm attributed to
Wylie et al. (1967)
'Rcpp' Bindings for the 'Corpus Workbench' ('CWB')
'Rcpp' Bindings for the C code of the 'Corpus Workbench' ('CWB'), an indexing and query engine to efficiently analyze large corpora (< https://cwb.sourceforge.io>). 'RcppCWB' is licensed under the GNU GPL-3, in line with the GPL-3 license of the 'CWB' (< https://www.r-project.org/Licenses/GPL-3>). The 'CWB' relies on 'pcre2' (BSD license, see < http://www.pcre.org/licence.txt>) and 'GLib' (LGPL license, see < https://www.gnu.org/licenses/lgpl-3.0.en.html>). See the file LICENSE.note for further information. The package includes modified code of the 'rcqp' package (GPL-2, see < https://cran.r-project.org/package=rcqp>). The original work of the authors of the 'rcqp' package is acknowledged with great respect, and they are listed as authors of this package. To achieve cross-platform portability (including Windows), using 'Rcpp' for wrapper code is the approach used by 'RcppCWB'.
Database Interface and MariaDB Driver
Implements a DBI-compliant interface to MariaDB (< https://mariadb.org/>) and MySQL (< https://www.mysql.com/>) databases.
Spherical Geometry Operators Using the S2 Geometry Library
Provides R bindings for Google's s2 library for geometric calculations on the sphere. High-performance constructors and exporters provide high compatibility with existing spatial packages, transformers construct new geometries from existing geometries, predicates provide a means to select geometries based on spatial relationships, and accessors extract information about geometries.
Generic Coordinate System Transformations Using 'PROJ'
A wrapper around the generic coordinate transformation software 'PROJ' that transforms coordinates from one coordinate reference system ('CRS') to another. This includes cartographic projections as well as geodetic transformations. The intention is for this package to be used by user-packages such as 'reproj', and that the older 'PROJ.4' and version 5 pathways be provided by the 'proj4' package.
Correcting Drift and Carry-over in Continuous Isotopic Measurements
A series of functions that allow an easy and fast correction for drift and carry-over in continuous isotopic measurements. This implementation provides queries allowing users to perform the implemented corrections according to their needs. These functions further enable the processing of large datasets and can provides apt visualizations of the corrections performed.
