Modified versions of the lag() and summary() functions: glag() and gsummary(). The prefix 'g' is a reminder of who to blame if things do not work as they should.

It is not very easy to define segments for y-axis in a 'ggplot2' plot. gg.gap() function in this package can carry it out.

Streamlines exploratory data analysis by providing a turnkey approach 
  to visualising n-dimensional data which graphically reveals correlative or associative relationships 
  between 2 or more features. Represents all dataset features as distinct, vertically 
  aligned bar or tile plots, with plot types auto-selected based on whether variables are categorical or numeric.

A 'ggplot2' extension providing an integrative framework for
    composable visualization, enabling the creation of complex multi-plot
    layouts such as insets, circular arrangements, and multi-panel compositions.
    Built on the grammar of graphics, it offers tools to align, stack, and nest
    plots, simplifying the construction of richly annotated figures for
    high-dimensional data contexts—such as genomics, transcriptomics, and
    microbiome studies—by making it easy to link related plots, overlay
    clustering results, or highlight shared patterns.

Providing publication-ready graphs for Multiple sequence alignment. Moreover, it provides a unique solution for visualizing the multiple sequence alignment without the need to do the alignment in each run which is a big limitation in other available packages.

'D&D' alignment charts show 9 boxes with values for good
    through evil and values for chaotic through lawful. This package
    easily creates these alignment charts from user-provided image paths
    and alignment values.

Extra geoms and scales for 'ggplot2', including geom_cloud(),
  a Normal density cloud replacement for errorbars;
  transforms ssqrt_trans and pseudolog10_trans, which are loglike but 
  appropriate for negative data; interp_trans() and warp_trans() which
  provide scale transforms based on interpolation;
  and an infix compose operator for scale transforms.
