rle2: Run Length Encoding with Indices

Description

Compute the lengths, values and indices of runs of equal values in a vector. This is a modifed version of base function rle().

Usage

rle2(x)
"print"(x, digits = getOption("digits"), prefix = "", ...)

Arguments

x

an atomic vector for rle(); an object of class "rle" for inverse.rle().

...

further arguments; ignored here.

digits

number of significant digits for printing, see print.default.

prefix

character string, prepended to each printed line.

Value

rle() returns an object of class "rle" which is a list with components:

Details

Missing values are regarded as unequal to the previous value, even if that is also missing.

inverse.rle() is the inverse function of rle2() and rle(), reconstructing x from the runs.

Examples

x <- rev(rep(6:10, 1:5))
rle(x)
## lengths [1:5]  5 4 3 2 1
## values  [1:5] 10 9 8 7 6
rle2(x)
## lengths: int [1:5] 5 4 3 2 1
## values : int [1:5] 10 9 8 7 6
## indices: int [1:5] 5 9 12 14 15
