benchmarks.rmdEach system is characterized by the operating system type, the CPU type, the mkin version, and, as in June 2022 the current R version lead to worse performance, the R version. A compiler was available, so if no analytical solution was available, compiled ODE models are used.
Every fit is only performed once, so the accuracy of the benchmarks is limited.
The following wrapper function for mmkin is used because the way the error model is specified was changed in mkin version 0.9.49.1.
if (packageVersion("mkin") > "0.9.48.1") {
mmkin_bench <- function(models, datasets, error_model = "const") {
mmkin(models, datasets, error_model = error_model, cores = 1, quiet = TRUE)
}
} else {
mmkin_bench <- function(models, datasets, error_model = NULL) {
mmkin(models, datasets, reweight.method = error_model, cores = 1, quiet = TRUE)
}
