Quae Postea

Description

For a list of multiple partial sequences (of vector objects), generate another list which, for each element, gives all elements that occur after it ("quae postea"). This is analogous to a recursive trace through all partial sequences from left to right. A final element "omega" is added to all sets to avoid empty vectors. See also quae_antea.

Usage

quae_postea(obj)

## S3 method for class 'list'
quae_postea(obj)

Arguments

obj	A list of vector objects which reperesent ordered sequences.

Value

A list of vector objects, which contain the elements that occur after any one given element in the input sequences.

Examples

x <- c("A", "B", "C")
y <- c("B", "D", "E", "C", "F")
z <- c("C", "G")
a <- list(x, y, z)
