rleDiff-class {Matrix} R Documentation

Class "rleDiff" of rle(diff(.)) Stored Vectors

Description

Class "rleDiff" is for compactly storing long vectors which mainly consist of linear stretches. For such a vector x, diff(x) consists of constant stretches and is hence well compressable via rle().

Objects from the Class

Objects can be created by calls of the form new("rleDiff", ...).

Currently experimental, see below.

Slots

first:

A single number (of class "numLike", a class union of "numeric" and "logical").

rle:

Object of class "rle", basically a list with components "lengths" and "values", see rle(). As this is used to encode potentially huge index vectors, lengths may be of type double here.

Methods

There is a simple show method only.

Note

This is currently an experimental auxiliary class for the class abIndex, see there.
