public abstract class REXPVector
extends REXP

abstract class representing all vectors in R

Field Summary

Fields inherited from class org.rosuda.REngine.REXP

attr, maxDebugItems

Constructor Summary

REXPVector()

REXPVector(REXPList attr)

Method Summary

boolean[]	isNA() returns a boolean vector of the same length as this vector with true for NA values and false for any other values
boolean	isVector() check whether the REXP object is a vector
abstract int	length() returns the length of the vector (i.e. the number of elements)
java.lang.String	toDebugString() returns representation that it useful for debugging (e.g. it includes attributes and may include vector values -- see REXP.maxDebugItems)
java.lang.String	toString() returns a string description of the object

Constructor Detail

REXPVector

public REXPVector()

REXPVector

public REXPVector(REXPList attr)

Method Detail

length

public abstract int length()

returns the length of the vector (i.e. the number of elements)

Overrides:

length in class REXP

Returns:

length of the vector

isVector

public boolean isVector()

Description copied from class: REXP

check whether the REXP object is a vector

Overrides:

isVector in class REXP

Returns:

true if the receiver is a vector, false otherwise

isNA

public boolean[] isNA()

returns a boolean vector of the same length as this vector with true for NA values and false for any other values

Overrides:

isNA in class REXP

Returns:

a boolean vector of the same length as this vector with true for NA values and false for any other values

toString

public java.lang.String toString()

Description copied from class: REXP

returns a string description of the object

Overrides:

toString in class REXP

Returns:

string describing the object - it can be of an arbitrary form and used only for debugging (do not confuse with REXP.asString() for accessing string REXPs)

toDebugString

public java.lang.String toDebugString()

Description copied from class: REXP

returns representation that it useful for debugging (e.g. it includes attributes and may include vector values -- see REXP.maxDebugItems)

Overrides:

toDebugString in class REXP

Returns:

extended description of the obejct -- it may include vector values
