Method new()

Create a new Rscript process.

Usage

rscript_process$new(options)

Arguments

options

A list of options created via rscript_process_options().

Method finalize()

Clean up after an Rsctipt process, remove temporary files.

Usage

rscript_process$finalize()

Method clone()

The objects of this class are cloneable with this method.

Usage

rscript_process$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples
