Sequence Check

Description

For a list of partial sequences (of vector objects), check to see that joint elements of each occur the same order. That is, for two sequences with elements A, B, C, D, E and B, D, F, E, all joint elements must occur in the same order to pass the check. Two sequences A, B, C, D, E and A, F, D, C, E would not pass this check as the elements C and D occur in different orders in either sequence.

Usage

seq_check(obj)

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

Arguments

obj	A list of vector objects which represent a sequence.

Details

Event names alpha and omega are reserved for the ultimate boundaries of the chronological framework and should not be used in naming events in sequences.

Value

TRUE or FALSE

Examples

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

seq_check(a)

z <- c("B", "F", "C")
b <- list(x, y, z)

seq_check(b)
