not(CT1, CT2)

Arguments

CT1

Coding of code one.

CT2

Coding of code two.

Examples

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))
