A set of fast and convenient functions to help conducting
    accessibility analyses. Given a pre-computed travel cost matrix and a
    land use dataset (containing the location of jobs, healthcare and
    population, for example), the package allows one to calculate
    accessibility levels and accessibility poverty and inequality. The
    package covers the majority of the most commonly used accessibility
    measures (such as cumulative opportunities, gravity-based and floating
    catchment areas methods), as well as the most frequently used
    inequality and poverty metrics (such as the Palma ratio, the
    concentration and Theil indices and the FGT family of measures).

Provides functions to produce accessible 'HTML' slides, 'HTML', 
    'Word' and 'PDF' documents from input 'R markdown' files. Accessible 'PDF' 
    files are produced only on a 'Windows' Operating System. One aspect of 
    accessibility is providing a headings structure that is recognised by a 
    screen reader, providing a navigational tool for a blind or 
    partially-sighted person. A key aim is to produce documents of different 
    formats easily from each of a collection of 'R markdown' source files. 
    Input 'R markdown' files are rendered using the render() function from the 
    'rmarkdown' package <https://cran.r-project.org/package=rmarkdown>. A 'zip' 
    file containing multiple output files can be produced from one function 
    call. A user-supplied template 'Word' document can be used to determine the 
    formatting of an output 'Word' document. Accessible 'PDF' files are 
    produced from 'Word' documents using 'OfficeToPDF' 
    <https://github.com/cognidox/OfficeToPDF>. A convenience function, 
    install_otp() is provided to install this software. The option to print 
    'HTML' output to (non-accessible) 'PDF' files is also available.

Provides a simple method to improve the accessibility of
    'rmarkdown' documents. The package provides functions for creating or
    modifying 'rmarkdown' documents, resolving known errors and alerts that
    result in accessibility issues for screen reader users.
