composeFromSource: Compose a Acumos microservice from its source file

In s-u/acumos: Acumos R interface

Description

composeFromSource generates everything necessary to create a Acumos microservice directly from a specifically written R file, representing the component source.

Usage

composeFromSource(
  file = "acumos.R",
  name = "R Component",
  outputfile = "component.zip",
  addSource = T
)

Arguments

file	string, name of component source file (an R script)
name	string, name of the component
outputfile	string, filename for the resulting component file
addSource	boolean, to add source file to the (ZIP) bundle or not

Value

Structure describing the component (parsed content of the JSON description).

Note

A regular component source file is an R script in which at least one of the three following functions are defined: acumos_predict, acumos_transform or acumos_fit. They respectively correspond to the functions predict, transform and fit of compose. In that script, if the functions acumos_generate, acumos_service or acumos_initialize are defined, they will also correspond to the other function type arguments of compose, namely generate, service and initialize.

All the R objects defined in that script are included as auxiliary objects that are to be passed to the global workspace of the component. They will fill the aux argument of compose.
