`cl`	A cluster object created by `makeCluster`, or an integer. It can also be `NULL`, see Details.
`seq`	A vector to split.
`fun`	A function or character string naming a function.
`cldata`	A list containing data. This will be assigned to an object `name` in the global environment (an already existing object with same name will be saved and replaced back in the end). This list is then exported to the cluster by `clusterExport`. Data in `cldata` can be used by `fun`.
`name`	Character, the name of `cldata` as to be assigned to the global environment and used in `fun`.
`use.env`	Logical, if `name` is to be treated as a list object or an environment.
`lib`	Character, name of package(s). Optionally packages can be loaded onto the cluster. More than one package can be specified as character vector. Packages already loaded are skipped.
`dir`	Working directory to use, if `NULL` working directory is not set on workers (default). Can be a vector to set different directories on workers.
`evalq`	Character, expressions to evaluate, e.g. for changing global options (passed to `clusterEvalQ`). More than one expressions can be specified as character vector.
`balancing`	Character, type of balancing to perform (see Details).
`size`	Vector of problem sizes (or relative performance information) corresponding to elements of `seq` (recycled if needed). The default `1` indicates equality of problem sizes.
`rng.type`	Character, `"none"` or the type of RNG on the workers (see `clusterSetupRNG`). The logical value `!(rng.type == "none")` is used for forking (e.g. when `cl` is integer).
`cleanup`	logical, if `cldata` should be removed from the workers after applying `fun`. If `TRUE`, effects of `dir` argument is also cleaned up.
`unload`	logical, if `pkg` should be unloaded after applying `fun`.
`envir`	environment to use when assigning data values.
`...`	Other arguments of `fun`, that are simple values and not objects. (Arguments passed as objects should be specified in `cldata`, otherwise those are not exported to the cluster by this function.)
