Binning and plotting functions for hexagonal bins.

Kernel density estimation with hexagonal grid for bivariate data.
      Hexagonal grid has many beneficial properties like equidistant neighbours
      and less edge bias, making it better for spatial analyses than the more
      commonly used rectangular grid.

Contains most of the hex font files from the 'GNU Unifont Project' <https://unifoundry.com/unifont/> compressed by 'xz'.  'GNU Unifont' is a duospaced bitmap font that attempts to cover all the official Unicode glyphs plus several of the artificial scripts in the '(Under-)ConScript Unicode Registry' <https://www.kreativekorp.com/ucsur/>.  Provides a convenience function for loading in several of them at the same time as a 'bittermelon' bitmap font object for easy rendering of the glyphs in an 'R' terminal or graphics device.

Provides functions to build and use equal-area hexagonal discrete
    global grids using the 'Snyder' 'ISEA' projection ('Snyder' 1992
    <doi:10.3138/27H7-8K88-4882-1752>). Implements the 'ISEA' discrete global grid
    system ('Sahr', 'White' and 'Kimerling' 2003 <doi:10.1559/152304003100011090>).
    Includes a fast 'C++' core for projection and aperture quantization, and
    'sf'/'terra'-compatible R wrappers for grid generation and coordinate assignment.
    Output is compatible with 'dggridR' for interoperability.

Helper functions for creating reproducible hexagon sticker purely in R.

Simple and integrated tool that automatically extracts and folds all hairpin sequences from raw genome-wide data. It predicts the secondary structure of several overlapped segments, with longer length than the mean length of sequences of interest for the species under processing, ensuring that no one is lost nor inappropriately cut.
