Running mean of a time series

running_mean() calculates the running mean in a vector with the given bin width.

Usage

running_mean(v, binwidth)

Arguments

v

The numeric vector.

binwidth

Numeric constant, the size of the bin, should be meaningful, i.e. smaller than the length of v.

Value

A numeric vector of length length(v)-binwidth+1

Details

The running mean of v is a w vector of length length(v)-binwidth+1. The first element of w id the average of the first binwidth elements of v, the second element of w is the average of elements 2:(binwidth+1), etc.
