Computes running mean of a vector or matrix, returning the values from each step.
running_mean(x, na.rm)A vector containing the recursive mean estimates.
A numeric vector, matrix, three dimensional array, or an mcmc object from

for array the sweep is done over the third dimension.
If TRUE, NA values in x are
omitted from the computation. Default is FALSE.
