cummean: Cumulative means

In bgreenwell/treemisc: Data Sets and Functions to Accompany "Tree-Based Methods for Statistical Learning in R"

Cumulative means

Description

Returns a vector whose elements are the cumulative means of the argument.

Usage

cummean(x)

Arguments

x	A numeric object.

Value

A vector of the same length and type as x (after coercion). Names are preserved.

An NA value in x causes the corresponding and following elements of the return value to be NA, as does integer overflow (with a warning).

Examples

x <- 1:10
cummean(x)
cumsum(x) / seq_along(x)  # equivalent using cumulative sums
