Visualize the objects in orbits in 2D and 3D. The packages is under developing to plot the orbits of objects in polar coordinate system. See the examples in demo.

R functions for generating and/or displaying random Chuck Norris 
  facts. Based on data from the 'Internet Chuck Norris database' ('ICNDb').

Flexible rounding functions for use in error detection. They were
    outsourced from the 'scrutiny' package.

A simple rounding function. The default round() function in R
    uses the IEC 60559 standard and therefore it rounds 0.5 to 0 and rounds
    -1.5 to -2.  The roundx() function accounts for this and helps
    to round 0.5 up to 1.

Detecting outliers using robust methods, 
 	i.e. the Median Absolute Deviation (MAD) for univariate outliers; Leys, Ley, Klein, Bernard, & Licata (2013) <doi:10.1016/j.jesp.2013.03.013>
        and the Mahalanobis-Minimum Covariance Determinant (MMCD) for multivariate outliers; Leys, C., Klein, O., Dominicy, Y. & Ley, C. (2018) <doi:10.1016/j.jesp.2017.09.011>.
        There is also the more known but less robust Mahalanobis distance method, only for comparison purposes.

In order to make sure that web request ends up in the correct
    handler function a router is often used. 'routr' is a package implementing a
    simple but powerful routing functionality for R based servers. It is a fully
    functional 'fiery' plugin, but can also be used with other 'httpuv' based
    servers.

Much as 'roxygen2' allows one to document functions in the same file as the function itself, 'roxut'  allows one to write the unit tests in the same file as the function.  Once processed, the unit tests are moved to the appropriate directory.  Currently supports 'testthat' and 'tinytest' frameworks. The 'roxygen2' package provides much of the infrastructure.

An extension for 'roxygen2' to embed 'Shinylive' applications
    in the package documentation.

Generate your Rd documentation, 'NAMESPACE' file, and
    collation field using specially formatted comments. Writing
    documentation in-line with code makes it easier to keep your
    documentation up-to-date as your requirements change. 'roxygen2' is
    inspired by the 'Doxygen' system for C++.
