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.
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.
