An interface to the powerful and fairly complete computer algebra system 'Maxima'.
    It can be used to start and control 'Maxima' from within R by entering 'Maxima' commands. 
    Results from 'Maxima' can be parsed and evaluated in R. 
    It facilitates outputting results from 'Maxima' in 'LaTeX' and 'MathML'. 
    2D and 3D plots can be displayed directly. 
    This package also registers a 'knitr'-engine enabling 'Maxima' code chunks 
    to be written in 'RMarkdown' documents.

Provides functions to read and write 'ImageJ' (<https://imagej.net>)
    Region of Interest (ROI) files, to plot the ROIs and to convert them to
    'spatstat' (<https://spatstat.org/>) spatial patterns.

A pure R implementation of the median cut algorithm.
    Extracts the dominant colors from an image, and turns them into
    a scale for use in plots or for fun!

The metrics() function calculates measures of scholarly impact. 
    These include conventional measures, such as the number of publications
    and the total citations to all publications, as well as modern and 
    robust metrics based on the vector of citations associated with each 
    publication, such as the h index and many of its variants or rivals.
    These methods are described in Ruscio et al. (2012) 
    <DOI: 10.1080/15366367.2012.711147>.

Tools for manipulating, exploring, and visualising  multiple-response data, including scored or ranked responses. Conversions to and from factors, lists, strings, matrices; reordering, lumping, flattening; set operations; tables; frequency and co-occurrence plots.

A programmatic interface to the API provided by the 'iNaturalist' website <https://www.inaturalist.org/> to download species occurrence data submitted by citizen scientists.
