9. def eval(snippet: String, evalOnly: Boolean = true): Any

   

   Evaluates snippet in the R interpreter.

   Evaluates snippet in the R interpreter.

   Returns null if evalOnly. If !evalOnly, the last result of the R expression is converted if possible. Conversion to integers, doubles, Booleans, and strings are supported, as are vectors (i.e. arrays) and matrices (i.e. retangular arrays of arrays) of these types. The static type of the result, however, is Any so using the method evalXY (where X is I, D, B, or S and Y is 0, 1, or 2) may be more convenient (e.g. evalD0).

10. def evalB0(snippet: String): Boolean

    

    Calls eval(snippet,true) and returns the result using getB0.

11. def evalB1(snippet: String): Array[Boolean]

    

    Calls eval(snippet,true) and returns the result using getB1.

12. def evalB2(snippet: String): Array[Array[Boolean]]

    

    Calls eval(snippet,true) and returns the result using getB2.

13. def evalD0(snippet: String): Double

    

    Calls eval(snippet,true) and returns the result using getD0.

14. def evalD1(snippet: String): Array[Double]

    

    Calls eval(snippet,true) and returns the result using getD1.

15. def evalD2(snippet: String): Array[Array[Double]]

    

    Calls eval(snippet,true) and returns the result using getD2.

16. def evalI0(snippet: String): Int

    

    Calls eval(snippet,true) and returns the result using getI0.

17. def evalI1(snippet: String): Array[Int]

    

    Calls eval(snippet,true) and returns the result using getI1.

18. def evalI2(snippet: String): Array[Array[Int]]

    

    Calls eval(snippet,true) and returns the result using getI2.

19. def evalR(snippet: String): RObject

    

    Calls eval(snippet,true) and returns the result using getR.

20. def evalS0(snippet: String): String

    

    Calls eval(snippet,true) and returns the result using getS0.

21. def evalS1(snippet: String): Array[String]

    

    Calls eval(snippet,true) and returns the result using getS1.

22. def evalS2(snippet: String): Array[Array[String]]

    

    Calls eval(snippet,true) and returns the result using getS2.

23. def exit(): Unit

    

    Closes the interface to the R interpreter.

25. def gc(): Unit

    

    Reclaims memory associated with all R references, including any instances of RObject that are still in memory.

26. def get(identifier: String, asReference: Boolean = false): (Any, String)

    

    Returns the value of identifier in the R interpreter.

    Returns the value of identifier in the R interpreter. The static type of the result is (Any,String), where the first element is the value and the second is the runtime type.

    If asReference=false, conversion to integers, doubles, Booleans, and strings are supported, as are vectors (i.e. arrays) and matrices (i.e. retangular arrays of arrays) of these types. Using the method getXY (where X is I, D, B, or S and Y is 0, 1, or 2) may be more convenient (e.g. getD0).

    If asReference=true, the value is merely wrapped using RObject and objects of any type are supported. Using the method getR may be more convenient.

27. def getB0(identifier: String): Boolean

    

    Calls get(identifier,false) and converts the result to a Boolean.

    Calls get(identifier,false) and converts the result to an Array[Boolean].

    Calls get(identifier,false) and converts the result to an Array[Boolean].

    Integers, doubles, Booleans, and strings are supported. Vectors (i.e. arrays) of these types are also supported by converting the first element. Matrices (i.e. rectangular arrays of arrays) are not supported.

    Calls get(identifier,false) and converts the result to an Array[Array[Boolean]].

    Matrices (i.e. rectangular arrays of arrays) of integers, doubles, Booleans, and strings are supported. Integers, doubles, Booleans, and strings themselves are not supported. Vectors (i.e. arrays) of these types are also not supported.
