systemR

Launches another R process from within R

Launches another R process from within R via system() by automatically locating the R executable, cf [1].

## Default S3 method:
systemR(command="", ..., Rcommand="R", verbose=FALSE)

`command`	A `character` string be appended to the `system`() call. If a `vector`, then the strings are concatenated separated with a space.
`...`	Additional arguments passed to `system`().
`Rcommand`	A `character` string specifying the basename of the R executable.
`verbose`	A `logical` or a `Verbose` object.

Returns what system() returns.
