The trapezoid package provides 'dtrapezoid', 'ptrapezoid', 'qtrapezoid',
    and 'rtrapezoid' functions for the trapezoidal distribution.

Pacote para a analise de experimentos com um ou dois fatores com
             testemunhas adicionais conduzidos no delineamento inteiramente 
             casualizado ou em blocos casualizados. 
             "Package for the analysis of one or two-way experiments with 
             additional controls conducted in a completely randomized design 
             or in a randomized block design".

Simple trustworthy utility functions to use TauDEM 
    (Terrain Analysis Using Digital Elevation Models <https://hydrology.usu.edu/taudem/taudem5/>) command-line interface.
    This package provides a guide to installation of TauDEM and its dependencies GDAL (Geopatial Data Abstraction Library) 
    and MPI (Message Passing Interface) for different operating systems.
    Moreover, it checks that TauDEM and its dependencies are correctly installed and included to the PATH, 
    and it provides wrapper commands for calling TauDEM methods from R.

Hospitals, hospital systems, and even trauma systems that
    provide care to injured patients may not be aware of robust metrics
    that can help gauge the efficacy of their programs in saving the lives
    of injured patients.  'traumar' provides robust functions driven by
    the academic literature to automate the calculation of relevant
    metrics to individuals desiring to measure the performance of their
    trauma center or even a trauma system.  'traumar' also provides some
    helper functions for the data analysis journey. Users can refer to the
    following publications for descriptions of the methods used in
    'traumar'.  TRISS methodology, including probability of survival, and
