Rolling Mean¶

Computes the rolling mean over a numeric vector.

Usage¶

rolling_mean(x, window_size, min_periods = window_size, assume_finite = FALSE)

Parameter	Description
`x`	A numeric vector of type double.
`window_size`	Positive integer window length.
`min_periods`	Minimum number of non-`NA` observations required in a window to return a result. Defaults to `window_size`.
`assume_finite`	If `TRUE`, assumes the input contains no `NA` values and uses a faster SIMD prefix-sum path. Passing `TRUE` when NA``s are present produces incorrect results. Defaults to ``FALSE.

A numeric vector with rolling mean values.

x <- as.double(c(1, 2, 3, 4))
rolling_mean(x, 3L)
