The R package pfm provides some utilities for fate modelling, including 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"))Alternatively you can install the package using the remotes package. Using quick = TRUE skips docs, multiple-architecture builds, demos, and vignettes.
remotes::install_github("jranke/pfm", quick = TRUE)Use
Please refer to the reference.
Examples
One recent 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.
