Useful utilities ['goodies'] from Seminar fuer Statistik ETH Zurich,
   some of which were ported from S-plus in the 1990s.
 For graphics, have pretty (Log-scale) axes eaxis(), an enhanced Tukey-Anscombe
   plot, combining histogram and boxplot, 2d-residual plots, a 'tachoPlot()',
   pretty arrows, etc.
 For robustness, have a robust F test and robust range().
 For system support, notably on Linux, provides 'Sys.*()' functions with
   more access to system and CPU information.
 Finally, miscellaneous utilities such as simple efficient prime numbers,
   integer codes, Duplicated(), toLatex.numeric() and is.whole().

A series of tools for analyzing Systems Factorial Technology data.  This includes functions for plotting and statistically testing capacity coefficient functions and survivor interaction contrast functions.  Houpt, Blaha, McIntire, Havig, and Townsend (2013) <doi:10.3758/s13428-013-0377-3> provide a basic introduction to Systems Factorial Technology along with examples using the sft R package.

Classes and methods for spatial objects that have a registered time 
    column, in particular for irregular spatiotemporal data. The time column can 
    be of any type, but needs to be ordinal. Regularly laid out spatiotemporal 
    data (vector or raster data cubes) are handled by package 'stars'.

Contains space filling based tools for
    machine learning and data mining. Some functions offer
    several computational techniques and deal with the out of
    memory for large big data by using the ff package.

Modern classes for tracking and movement data, building
    on 'sf' spatial infrastructure, and early theoretical work from
    Turchin (1998, ISBN: 9780878938476), and Calenge et al. (2009)
    <doi:10.1016/j.ecoinf.2008.10.002>. Tracking data are series of
    locations with at least 2-dimensional spatial coordinates (x,y), a
    time index (t), and individual identification (id) of the object
    being monitored; movement data are made of trajectories, i.e. the
    line representation of the path, composed by steps (the
    straight-line segments connecting successive locations). 'sftrack'
    is designed to handle movement of both living organisms and
    inanimate objects.
