Return a matrix, give a summary of inter-codes relationship.
crossCodes(relation=c("overlap","inclusion","exact","proximity"),codeList=NULL,
data=GetCodingTable(),print=TRUE,...)crossTwoCodes(cid1,cid2,data,relation=c("overlap","inclusion","exact","proximity"),...)
The relation between codes
A character vector, the codes list on which the inter-code relationship is based
Data frame returned by getCodingTable
,may be subset of the full coding table
When TRUE, print the results automatically
Length-1 code id. It is numeric.
Length-1 code id. It is numeric.

is not used yet.
For crossCodes
, it is a matrix. The upper matrix contains the
number of codings fitting the relation between the respective two
codes. the lower matrix is all NA. rownames of the matrix is the name of
the codes, and the colnames of the matrix is the corresponding id of
codes.
For crossCodes
, it is a numeric vector.
The inter-codes relationship calculation is based on the relationship between the associated codings of the codes.
Giving the code name list (a character list), crossCodes
returns
the inter-relationship of 2 or more than 2 codes. crossCodes
make heavy use of for loops, so it may take a while to get the result
when the coding table is large.
crossTwoCodes
returns the summary of inter-codes relationship of two
codes based on the code id (each code id is a length-1 integer vector).
