Fit one or more kinetic models with one or more state variables to one or more datasets

This function calls mkinfit on all combinations of models and datasets specified in its first two arguments.

mmkin(models = c("SFO", "FOMC", "DFOP"), datasets,
  cores = round(detectCores()/2), cluster = NULL, ...)

Arguments

models	Either a character vector of shorthand names like c("SFO", "FOMC", "DFOP", "HS", "SFORB"), or an optionally named list of mkinmod objects.
datasets	An optionally named list of datasets suitable as observed data for mkinfit.
cores	The number of cores to be used for multicore processing. This is only used when the cluster argument is NULL. On Windows machines, cores > 1 is not supported, you need to use the cluster argument to use multiple logical processors.
cluster	A cluster as returned by makeCluster to be used for parallel execution.
...	Further arguments that will be passed to mkinfit.

Value

A matrix of mkinfit objects that can be indexed using the model and dataset names as row and column indices.
