Описание тега rscript

Rscript (Rscript.exe on Windows) is a binary front-end to R, for use in scripting applications. It is included in the core R distribution since version 2.5.0.

littler is an alternative front end to R for use in '#!' scripts.

Example:

Rscript

#! /path/to/Rscript
args <- commandArgs()
args <- args[-(1:match("--args", args)]
cat('hello world!', args, "\n")

littler

#! /path/to/r
cat('hello world!', argv, "\n")

Rscript passes all script arguments to R as additional elements to the vector returned from commandArgs().

littler provides convenience by assigning the script arguments to an argv vector and placing that into the global environment, a convention followed by other popular scripting languages.
