About this vignette

The aim of this vignette is to provide users with a rough estimation of computing times for simulation models included in package medfate.

The results presented here were obtained using 1 year of simulation with the example data sets on a laptop (16 GiB memory and 11th Gen Inter Core I5 processor @ 2.40 GHz x 8) with Ubuntu Linux OS.

Table of computational times

Computational times were estimated using system.time(), are in seconds and are shown by package version.
