simmer is a process-oriented and trajectory-based Discrete-Event Simulation (DES) package for R. Designed to be a generic framework like SimPy or SimJulia, it leverages the power of Rcpp to boost the performance and turning DES in R feasible. As a noteworthy characteristic, simmer exploits the concept of trajectory: a common path in the simulation model for entities of the same type. It is pretty flexible and simple to use, and leverages the chaining/piping workflow introduced by the magrittr package.

vignette(package = "simmer")Installation
Install the release version from CRAN:
install.packages("simmer")The installation from GitHub requires the remotes package.
remotes::install_github("r-simmer/simmer")Please note that the package contains some C++ code and thus you need a development environment to build the package (e.g. Rtools for Windows).
