Description

Basic utilities for rle packing and unpacking and apropriate methods for rev() and unique().

Usage

rlepack(x, ...)
# S3 method for integer
rlepack(x, pack = TRUE, ...)
rleunpack(x)
# S3 method for rlepack
rleunpack(x)
# S3 method for rlepack
rev(x)
# S3 method for rlepack
unique(x, incomparables = FALSE, ...)
# S3 method for rlepack
anyDuplicated(x, incomparables = FALSE, ...)

Value

A list with components:

• first: the first element of the packed sequence

• dat: either an object of class rle() or the complete input vector x if rle-packing is not efficient

• last: the last element of the packed sequence

Arguments
