rle
Run Length Encoding and Decoding
Description
Computes the length and the value of runs of the same value in a
vector.
Usage
rle(x)
print.rle(x, digits = getOption("digits"), prefix = "", ...)
inverse.rle(x, ...)
Arguments
| x |
for rle, a vector object.
For print.rle and inverse.rle, an rle object.
|
| digits |
the number of digits displayed for a numeric values component.
|
| prefix |
the prefix for each line.
|
| ... |
reserved for future use. Ignored in this version.
|
Value
| rle() | returns an rle object, which is a list
containing:
- lengths: a vector containing the length of each run.
- values: a vector the same length as lengths,
with the values of each run.
|
| print.rle() | (a print S3 method for rle
object.) Prints the object's information: lengths and
values. |
| inverse.rle() | returns the rle object of a vector
containing the values that replicates a certain number of runs. |
