\title{Fit one or more kinetic models with one or more state variables to one or
more datasets}
\usage{
mmkin(
models = c("SFO", "FOMC", "DFOP"),
datasets,
cores = if (Sys.info()["sysname"] == "Windows") 1 else parallel::detectCores(),
cluster = NULL,
...
)
\method{print}{mmkin}(x, ...)
}
\arguments{
\item{models}{Either a character vector of shorthand names like
\code{c("SFO", "FOMC", "DFOP", "HS", "SFORB")}, or an optionally named
list of \code{\link{mkinmod}} objects.}
\item{datasets}{An optionally named list of datasets suitable as observed
data for \code{\link{mkinfit}}.}
\item{cores}{The number of cores to be used for multicore processing. This
is only used when the \code{cluster} argument is \code{NULL}. On Windows
machines, cores > 1 is not supported, you need to use the \code{cluster}
argument to use multiple logical processors. Per default, all cores
detected by \code{\link[parallel:detectCores]{parallel::detectCores()}} are used, except on Windows where
the default is 1.}
\item{cluster}{A cluster as returned by \code{\link{makeCluster}} to be used
for parallel execution.}
\item{\dots}{Not used.}
\item{x}{An \link{mmkin} object.}
}
\value{
A two-dimensional \code{\link{array}} of \code{\link{mkinfit}}
objects and/or try-errors that can be indexed using the model names for the
first index (row index) and the dataset names for the second index (column
index).
}
\description{
This function calls \code{\link{mkinfit}} on all combinations of models and
datasets specified in its first two arguments.
