cm_combine.dummy: Find Co-occurrence Between Codes

In trinker/qdap2: Bridging the gap between qualitative data and quantitative analysis

Description

Combine code columns where they co-occur.

Usage

  cm_combine.dummy(cm.l2d.obj, combine.code,
    rm.var = "time", overlap = TRUE)

Arguments

cm.l2d.obj	An object from cm_long2dummy.
combine.code	A list of named character vectors of at least two code column names to combine
rm.var	Name of the repeated measures column. Default is "time".
overlap	logical, integer or character of binary operator + integer. If TRUE finds the overlap. If FALSE finds anywhere any of the codes occur. If integer finds that exact combination of overlaps. If character must be a logical vector c(>, <, =<, =>, ==, !=) followed by an integer.

Value

Returns a dataframe with co-occurrences of provided code columns.

    AA = qcv(terms="1:10"),
    BB = qcv(terms="1:2, 3:10, 19"),
    CC = qcv(terms="1:3, 5:6")
)

foo2  <- list(
    AA = qcv(terms="4:8"),
    BB = qcv(terms="1:4, 10:12"),
    CC = qcv(terms="1, 11, 15:20"),
    DD = qcv(terms="")
)


(x <- cm_range2long(foo))
(D1 <- cm_long2dummy(x))

(z <- cm_range2long(foo, foo2, v.name="time"))
(D2 <- cm_long2dummy(z, "time"))
cm_combine.dummy(D1, combine.code = list(AB=qcv(AA, BB)))
cm_combine.dummy(D1, combine.code = list(AB=qcv(AA, BB)), overlap="==1")
cm_combine.dummy(D1, combine.code = list(AB=qcv(AA, BB)), overlap="!=1")
D1 <- cm_combine.dummy(D1, combine.code = list(AB=qcv(AA, BB)), overlap=0)
D1 <- cm_combine.dummy(D1, combine.code = list(CAB=qcv(AB, CC)), overlap=FALSE)

combines <- list(AB=qcv(AA, BB), ABC=qcv(AA, BB, CC))
cm_combine.dummy(D1, combine.code = combines)
cm_combine.dummy(D2, combine.code = combines)
