Accesses high resolution raster maps using the OpenStreetMap
    protocol. Dozens of road, satellite, and topographic map servers are directly
    supported, including Apple, Mapnik, Bing, and stamen. Additionally raster maps
    may be constructed using custom tile servers.  Maps can be
    plotted using either base graphics, or ggplot2. This package is not affiliated
    with the OpenStreetMap.org mapping project.

Setup and connect to 'OpenTripPlanner' (OTP) <http://www.opentripplanner.org/>.
    OTP is an open source platform for multi-modal and multi-agency
    journey planning written in 'Java'. The package allows you to manage a local version or 
    connect to remote OTP server to find walking, cycling, driving, or transit routes.
    This package has been peer-reviewed by rOpenSci (v. 0.2.0.0).

Implements multiple existing open-source algorithms for coding cause of death from verbal autopsies. The methods implemented include 'InterVA4' by Byass et al (2012) <doi:10.3402/gha.v5i0.19281>, 'InterVA5' by Byass at al (2019) <doi:10.1186/s12916-019-1333-6>, 'InSilicoVA' by McCormick et al (2016) <doi:10.1080/01621459.2016.1152191>, 'NBC' by Miasnikof et al (2015) <doi:10.1186/s12916-015-0521-2>, and a replication of 'Tariff' method by James et al (2011) <doi:10.1186/1478-7954-9-31> and Serina, et al. (2015) <doi:10.1186/s12916-015-0527-9>. It also provides tools for data manipulation tasks commonly used in Verbal Autopsy analysis and implements easy graphical visualization of individual and population level statistics. The 'NBC' method is implemented by the 'nbc4va' package that can be installed from <https://github.com/rrwen/nbc4va>. Note that this package was not developed by authors affiliated with the Institute for Health Metrics and Evaluation and thus unintentional discrepancies may exist in the implementation of the 'Tariff' method.

Simplifies the creation of Excel .xlsx files by providing a
    high level interface to writing, styling and editing worksheets.
    Through the use of 'Rcpp', read/write times are comparable to the
    'xlsx' and 'XLConnect' packages with the added benefit of removing the
    dependency on Java.
