In RDataCanvas: Basic Runtime Support for Datacanvas.io

Description

This function will create a runtime object(in S3) for module. In order to create a DCRuntime object, we should provide the following items:

spec.json

which defines the inputs/outputs/parameters of the module.

zetrt.json

the parameters at runtime.

arguments

the arguments from command line. In the format, like "A=1".

Usage

DCRuntime(spec_json = "spec.json", zetrt_json = NULL, args = NULL)

Arguments

spec_json	The path for "spec.json".
zetrt_json	The path for "zetrt.json". The default is NULL, which means we can get it from system environment variable "ZETRT".
args	The arguments for Input/Output with format like "A=1". The default is NULL, which means we can get it from command line arguments with "commandArgs".

Value

A S3 object.
