merge_identifiers: Merge group identifiers

Description

Consolidate two group identifiers.

Usage

merge_ids(...)
# S3 method for default
merge_ids(id1, id2, tie_sort = NULL, expand = TRUE, shrink = FALSE, ...)
# S3 method for pid
merge_ids(id1, id2, tie_sort = NULL, expand = TRUE, shrink = FALSE, ...)
# S3 method for epid
merge_ids(id1, id2, tie_sort = NULL, expand = TRUE, shrink = FALSE, ...)
# S3 method for pane
merge_ids(id1, id2, tie_sort = NULL, expand = TRUE, shrink = FALSE, ...)

Arguments

...

Other arguments

id1

[integer|epid|pid|pane].

id2

[integer|epid|pid|pane].

tie_sort

[atomic]. Preferential order for breaking tied matches.

expand

[logical]. If TRUE, id1 gains new records if id2 indicates a match. Not interchangeable with shrink.

shrink

[logical]. If TRUE, id1 loses existing records id2 does not indicate a match. Not interchangeable with expand.

Details

Groups in id1 are expanded or shrunk by groups in id2.

A unique group with only one record is considered a non-matching record.

Note that the expand and shrink features are not interchangeable. The outcome when shrink is TRUE is not the same when expand is FALSE. See Examples.

Examples

id1 <- rep(1, 5)
id2 <- c(2, 2, 3, 3, 3)
merge_ids(id1, id2, shrink = TRUE)

id1 <- c(rep(1, 3), 6, 7)
id2 <- c(2,2,3,3,3)
merge_ids(id1, id2, shrink = TRUE)
merge_ids(id1, id2, expand = FALSE)

id1 <- rep(1, 5)
id2 <- c(1:3, 4, 4)
merge_ids(id1, id2, shrink = TRUE)
merge_ids(id1, id2, expand= FALSE)
