R Documentation

Get all unique cases of a list field by expression

Description

Get all unique cases of a list field by expression

Usage

list.cases(.data, expr, simplify = TRUE, sorted = TRUE)

Arguments

`.data`	A `list` or `vector`
`expr`	A lambda expression. The function will returns all cases of the elements if `expr` is missing.
`simplify`	`logical`. Should atomic vectors be simplified by `unlist`?
`sorted`	`logical`. Should the cases be sorted in ascending order?

Examples

x <- list(p1 = list(type='A',score=list(c1=10,c2=8)),
       p2 = list(type='B',score=list(c1=9,c2=9)),
       p3 = list(type='B',score=list(c1=9,c2=7)))
list.cases(x,type)
list.cases(x,mean(unlist(score)))

foo <- list(x = LETTERS[1:3], y = LETTERS[3:5])
list.cases(foo)
