Return smoothed averages of vector

Description

This function calculates a simple rolling mean in base R. It is useful for calculating route characteristics such as mean distances of segments and changes in gradient.

Usage

route_rolling_average(x, n = 3)

Arguments

x

Numeric vector to smooth

n

The window size of the smoothing function. The default, 3, will take the mean of values before, after and including each value.
