Compute the lengths, values and indices of runs of equal values in a vector. This is a modifed version of base function rle().
rle()
rle2(x)# S3 method for rle2 print(x, digits = getOption("digits"), prefix = "", ...)
# S3 method for rle2 print(x, digits = getOption("digits"), prefix = "", ...)
rle() returns an object of class "rle" which is a list with components:
"rle"
an integer vector containing the length of each run.
a vector of the same length as lengths with the corresponding values.
lengths
an atomic vector for rle(); an object of class "rle" for inverse.rle().
inverse.rle()
further arguments; ignored here.
number of significant digits for printing, see print.default.
print.default
character string, prepended to each printed line.
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.
rle2()
x
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
