How do I find the rolling mean since the beginning of data using R?

Question

I am trying to find the rolling mean since the beginning of the data:

samp <- structure(list(samp = c(0.25, 0.4868, 0.6043, 0.5184, -0.3572, 
0.4685, 0.8264,          


        

Answer 1

You could use cummean from dplyr.

cummean(samp$samp)
