relation {RQDA} | R Documentation |
To calculate the relation between two codings, given the coding indexes.
relation(index1, index2)
index1 |
The first coding index, it is length-2 integer vector with the first element (index1[1]) less than the second element (index1[2]). |
index2 |
The second coding index, it is length-2 integer vector with the first element (index2[1]) less than the second element (index2[2]). |
The relation between two codings can be any of inclusion, overlap, exact (special case of inclusion and overlap) and proximity (Neither overlap nor inclusion).
A 6-element list:
Relation |
Length-1 character, standing for the type of relation. It may be one of inclusion, overlap, exact or proximity. |
OverlapIndex |
Length-2 vector, the index of overlapping between two coding indexes. It is c(NA,NA) when relation is proximity. |
UnionIndex |
Length-2 vector, the index of union of the two coding indexes. It is c(NA,NA) when relation is proximity. |
Distance |
Distance of two coding indexes. It is NA when relation is not proximity. |
WhichMin |
Which argument (index1 or index2) has the minimum value. If both have the same minmum value, return NA. |
WhichMax |
Which argument (index1 or index2) has the maximum value. If both have the same maxmum value, return NA. |
