trimean

trimean.default

Robust centrality measure estimated as the weighted average of
the three quartiles: \((Q_1 + 2Q_2 + Q_3) / 4\), where
\(Q_1, Q_2\) and \(Q_3\) are the first, second and third
quartiles respectively.

Data sets on various litter types like beach litter, riverain
litter, floating litter, and seafloor litter are rapidly growing. This
package offers a simple user interface to analyse these litter data in
a consistent and reproducible way. It also provides functions to
facilitate several kinds of litter analysis, e.g., trend analysis,
power analysis, and baseline analysis. Under the hood, these functions
are also used by the user interface. See Schulz et al. (2019)
<doi:10.1016/j.envpol.2019.02.030> for details. MS-Windows users are
advised to run 'litteR' in 'RStudio'. See our vignette: Installation manual
for 'RStudio' and 'litteR'.
