Spell checking common document formats including latex, markdown, manual pages,
    and description files. Includes utilities to automate checking of documentation and 
    vignettes as a unit test during 'R CMD check'. Both British and American English are 
    supported out of the box and other languages can be added. In addition, packages may
    define a 'wordlist' to allow custom terminology without having to abuse punctuation.

Automatically replaces "misspelled" words in a character vector
    based on their string distance from a list of words sorted by their frequency
    in a corpus. The default word list provided in the package comes from 
    the Corpus of Contemporary American English. Uses the Jaro-Winkler distance
    metric for string similarity as implemented in van der Loo (2014) 
    <doi:10.32614/RJ-2014-011>. The word frequency data is derived from 
    Davies (2008-) "The Corpus of Contemporary American English (COCA)" 
    <https://www.english-corpora.org/coca/>.

This implementation of the Empirical Mode Decomposition (EMD) works in 2 dimensions simultaneously, and 
    can be applied on spatial data. It can handle both gridded or un-gridded datasets.

Provides some easy-to-use functions to interpolate species range based on species occurrences and to estimate centers of biodiversity.

Implements spatial error estimation and
    permutation-based variable importance measures for predictive models
    using spatial cross-validation and spatial block bootstrap.

Performs non-parametric tests of parametric specifications.
    Five tests are available. 
    Specific bandwidth and kernel methods can be chosen along with many other options. 
    Allows parallel computing to quickly compute p-values based on the bootstrap.
