  "Description": "Data sets on various litter types like beach litter,\nriverain litter, floating litter, and seafloor litter are\nrapidly growing. This package offers a simple user interface to\nanalyse these litter data in a consistent and reproducible way.\nIt also provides functions to facilitate several kinds of\nlitter analysis, e.g., trend analysis, power analysis, and\nbaseline analysis. Under the hood, these functions are also\nused by the user interface. See Schulz et al. (2019)\n<doi:10.1016/j.envpol.2019.02.030> for details. MS-Windows\nusers are advised to run 'litteR' in 'RStudio'. See our\nvignette: Installation manual for 'RStudio' and 'litteR'.",
