The R package pfm provides some utilities for fate modelling, including simple PEC calculation routines and some routines for dealing with FOCUS pesticide fate modelling tools (currently only TOXSWA cwa and out files), made available under the GNU public license.
Installation
The easiest way to install the package is probably to use the r-universe repo:
install.packages("pfm",
repos = c("https://jranke.r-universe.dev", "https://cran.r-project.org"))The packages at R-universe are provided with a slight delay. Alternatively, you can install the package directly from github, e.g. by using pak.
# install.packages("pak")
pak::pak("jranke/pfm")Use
Please refer to the reference.
Examples
One nice example of the usage of this package is the visualisation of a time weighted average for a sawtooth curve obtained from several overlays of mkinfit predictions as shown here.
Applications
Calculations of predicted environmental concentrations using this package have been used in some publications by Agroscope.
