RAttributes

RAttributes[atts]

an RLink container for attributes of R objects.

Details and Options

  • atts must be a sequence of zero, one, or more delayed rules, of the form name :> value, where name must be a string name of an attribute, and value can be any valid R object representation, which RLink can handle.
  • RAttributes is not normally used as a standalone expression, but rather as a part of expressions with heads RVector or RList.
  • For R vectors, the attribute dim is not included in RAttributes in the short form of R object representation, but is included in the long (full) form.

Examples

Basic Examples  (3)

Wolfram Language code: Needs["RLink`"] InstallR[]

This represents the full internal form of a matrix:

Wolfram Language code: vecff = RVector["integer", {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, RAttributes["dim" :> RVector["integer", {2, 5}, RAttributes[]]]]

This is equivalent to the following short form:

Wolfram Language code: FromRForm[vecff]

The following expression represents the full internal form of an R vector with an additional names attribute:

Wolfram Language code: vecAttff = RVector["integer", {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, RAttributes["dim" :> RVector["integer", {2, 5}, RAttributes[]], "names" :> RVector["character", {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j"}, RAttributes[]] ]]

This is equivalent to the following short form:

Wolfram Language code: FromRForm[vecAttff ]

You can send this vector to R:

Wolfram Language code: RSet["vecAtt", vecAttff ]

This returns the attributes of the vector used above, fetched from R:

Wolfram Language code: atts = REvaluate["attributes(vecAtt)"]

Looking at the internal form of this answer, you can see that in R, attributes are stored in a list:

Wolfram Language code: ToRForm[atts]
