windows: Map a function over an Rle in windows

In sa-lee/superintronic: Tools for Working with Intron Signal

Description

Map a function over an Rle in windows

Usage

tile_rle(.x, .size = 1L, .fun, ...)

stretch_rle(.x, .size = 1L, .step = 1L, .fun, ...)

roll_rle(.x, .size = 1L, .step = 1L, .fun, ...)

Arguments

.x	An atomic vector or Rle object.
.size	The (integer) size of the window.
.fun	A function
...	Additional arguments passed on to the mapped function
.step	The (integer) amount to shift the start of the window by.

Details

The map functions apply a function over non-overlapping windows [tile_rle()], overlapping windows [roll_rle()], and windows with a fixed start but increasing width stretch_rle()

Examples

x <- S4Vectors::Rle(1:10, 1:10)
tile_rle(x, .size = 2, mean)
roll_rle(x, .size = 2, .step = 1, mean)
stretch_rle(x, .size = 1, .step = 2, mean)
