Figures rendered on graphics devices are usually 
 rescaled to fit pre-determined device dimensions. 'plotscale' 
 implements the reverse: desired plot dimensions are specified 
 and device dimensions are calculated to accommodate marginal
 material, giving consistent proportions for plot elements.
 Default methods support grid graphics such as lattice and ggplot.
 See "example('devsize')" and "vignette('plotscale')".

A framework for creating interactive figures for data exploration. 
    All plots are automatically linked and support several kinds of interactive features,
    including selection, zooming, panning, and parameter manipulation. The figures
    can be interacted with either manually, using a mouse and a keyboard, 
    or by running code from inside an active R session.

Contains a graphical user interface to generate the diagnostic
    plots proposed by Bauer (2005; <doi:10.1207/s15328007sem1204_1>), 
    Pek & Chalmers (2015; <doi:10.1080/10705511.2014.937790>), and
    Pek, Chalmers, R. Kok, & Losardo (2015; <doi:10.3102/1076998615589129>) to investigate
    nonlinear bivariate relationships in latent regression models using structural
    equation mixture models (SEMMs).

Provides high-level API and a wide range of options to create stunning, publication-quality plots effortlessly.
    It is built upon 'ggplot2' and other plotting packages, and is designed to be easy to use and to work seamlessly with 'ggplot2' objects.
    It is particularly useful for creating complex plots with multiple layers, facets, and annotations.
    It also provides a set of functions to create plots for specific types of data, such as Venn diagrams, alluvial diagrams, and phylogenetic trees.
    The package is designed to be flexible and customizable, and to work well with the 'ggplot2' ecosystem.
    The API can be found at <https://pwwang.github.io/plotthis/reference/index.html>.

Annotate plots with legends for continuous variables and colour
  spectra using the base graphics plotting tools; and manipulate irregular
  polygons. Includes palettes for colour-blind viewers.
