REnvironment

REnvironment[]

a container used by RLink to represent any R environment.

Details and Options

Only the global R environment is fully supported. All other R environments are still represented by REnvironment[], but the specific information about them is lost. Therefore, R objects whose Wolfram Language representation contains references to non-global R environments cannot generally be correctly exported back to R.
Like RCode, REnvironment is a head providing representation rather than equivalence. Exporting to R objects previously imported to the Wolfram Language (or their parts) containing any of these heads is not guaranteed to produce equivalent objects in the R workspace.
Expressions with the REnvironment head transform trivially (are left unchanged) by the functions ToRForm and FromRForm.

This loads RLink:

Wolfram Language code:

Needs["RLink`"]
InstallR[]

This creates a simple linear model:

Wolfram Language code:

lm = REvaluate["
{
	x <- 1:5
	y <- 3 * x + 2 
	linm <- lm(y~x)
}"];

The result is a rather complex R object:

Wolfram Language code: lm // Short[#, 15] &

Some parts of this object contain explicit reference to an R environment:

Wolfram Language code: Cases[lm, _[___, _REnvironment, ___], Infinity]

This can also be seen as follows:

Wolfram Language code: REvaluate["linm$terms"]
