RList |
asList()
returns the contents as a (named) list (if supported by the represented object) |
java.lang.Object |
asNativeJavaObject()
attempt to represent the REXP by a native Java object and return it. |
boolean |
isList()
check whether the REXP object is a list (either generic vector or a pairlist - i.e. |
boolean |
isRecursive()
check whether the REXP object is a recursive obejct |
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 |
