Ops.codings: Boolean operation on codings.
In RQDA: R-based Qualitative Data Analysis

Description Usage Arguments Details Value Author(s) See Also Examples

Return the result codings of the Boolean operation.

and(CT1, CT2)

or(CT1, CT2)

not(CT1, CT2)

`CT1`	Coding of code one.
`CT2`	Coding of code two.

CT1 and CT2 are subset of getCodingTable of a specific code or returned value of getCodingsByOne. In former situation, only columns of "index1", "index2","fid","filename" from CT1 and CT2 are used by this function.

These functions are the same as %and%, %or%, %not%.

An object of class "codingsByOne" and "data.frame". It consists:

`index1`
`index2`
`fid`
`filename`
`rowid`
`coding`	The codings, or the text segements.

## Not run: 
a <- getCodingTable()
c1 <- subset(a,cid==6)
c2 <- subset(a,cid==24)
ans <- and(c1, c2)
ans ## put it into a widget for inspection

## another way to do the same
and(getCodingsByOne(6), getCodingsByOne(24))

## or operator
or(getCodingsByOne(6), getCodingsByOne(24))

## not operator
not(getCodingsByOne(6), getCodingsByOne(24))
