Provides two methods of plotting categorical scatter plots such
    that the arrangement of points within a category reflects the density of
    data at that region, and avoids over-plotting.

A 'ggplot2' based implementation of biplots, giving a representation of a dataset in
    a two dimensional space accounting for the greatest variance, together with variable vectors
    showing how the data variables relate to this space. It provides a 
    replacement for stats::biplot(), but with many enhancements to control the analysis and
    graphical display. It implements 
    biplot and scree plot methods which can be used with the results of prcomp(), princomp(),
    FactoMineR::PCA(), ade4::dudi.pca() or MASS::lda() and can be customized using 'ggplot2' techniques.

Wrapper 'ggplot2' functions for publication-quality visualisation. 
    Aligned with 'ggplot2' and 'tidyverse'. Covers much of what 'ggplot2' does.

Algebra of operations for blending, copying, adjusting, and 
    compositing layers in 'ggplot2'. Supports copying and adjusting the 
    aesthetics or parameters of an existing layer, partitioning a layer 
    into multiple pieces for re-composition, applying affine transformations
    to layers, and combining layers (or partitions of layers) using blend modes
    (including commutative blend modes, like multiply and darken). Blend 
    mode support is particularly useful for creating plots with overlapping 
    groups where the layer drawing order does not change the output; 
    see Kindlmann and Scheidegger (2014) <doi:10.1109/TVCG.2014.2346325>.

Provides a 'shiny'-based layout editor for arranging 'R' plot
    objects on a fixed-size canvas. It supports 'ggplot2' plots, 'graphics'
    functions and recorded plots, 'pheatmap' objects, 'ComplexHeatmap' objects,
    'grid' grobs, 'gtable' objects, and local raster images, with live preview
    and PDF or PNG export.

A set of geometries to make line plots a little bit nicer. Use
    along with 'ggplot2' to:
    - Improve the clarity of line plots with many overlapping lines
    - Draw more realistic worms.
