Hello R specialists, I am using the runmean function to get the moving averages of a time serie. Here is the code that I enter: ma<-runmean(na.remove(myTimeSerie),20,align="right",endrule="NA") I get the vector that I want except for one detail: the first 20 values are supposed to be NAs but I get a value at the 10th element while it should be a NA value as well. Any idea about what it could be?
