list.class: Classify list elments into unique but non-exclusive cases

In rlist: A Toolbox for Non-Tabular Data Manipulation

Description

In non-tabular data, a certain field may take multiple values in a collection non-exclusively. To classify these elements into different cases, this function detects all possible cases and for each case all elements are examined whether to belong to that case.

Usage

list.class(.data, ..., sorted = TRUE)

Arguments

.data	A list or vector
...	keys
sorted	TRUE to sort the group keys. Ignored when the key has multiple entries.

Value

a list of possible cases each of which contains elements belonging to the case non-exclusively.

Examples

x <-
  list(
    p1=list(name='Ken',age=24,
      interest=c('reading','music','movies'),
      lang=list(r=2,csharp=4,python=3)),
    p2=list(name='James',age=25,
      interest=c('sports','music'),
      lang=list(r=3,java=2,cpp=5)),
    p3=list(name='Penny',age=24,
      interest=c('movies','reading'),
      lang=list(r=1,cpp=4,python=2)))
list.class(x,interest)
list.class(x,names(lang))
