Binary operations of RQDA.vector or codingsByOne.

e1 %and% e2

e1 %or% e2

e1 %not% e2

`e1`	a RQDA object.
`e2`	a RQDA object.

e1 and e2 can be objects of class "RQDA.vector" includes classes of "fileId", "fileName", "caseId", "caseName". They can be objects of class "codingsByOne", see getCodingsByOne. e1 and e2 must be the same class.

For class of "RQDA.vector", %and% is the intersect of e1 and e2. %or% is the union of e1 and e2. %not% is the defined as setdiff(e1, e2).

an object with the same structure and class of e1 and e2.
