| rleDiff-class {Matrix} | R Documentation |
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 can be created by calls of the form new("rleDiff", ...).
Currently experimental, see below.
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.
There is a simple show method only.
This is currently an experimental auxiliary class
for the class abIndex, see there.
showClass("rleDiff")
ab <- c(abIseq(2, 100), abIseq(20, -2))
ab@rleD # is "rleDiff"
