I don't know if this is what you are after, but have a look at: rollmean in the zoo package hth Stephen On Fri, Aug 20, 2010 at 2:47 PM, Hall, Ken (CDC/OSELS/NCPHI) wrote: > I am working on a simple pilot project comparing the capability of SQL, > SAS and R to perform a rolling mean per the fol

[R] rollmean help (or similar function)

I am working on a simple pilot project comparing the capability of SQL, SAS and R to perform a rolling mean per the following instructions. I have completed the SQL and SAS analysis, so now it's R's turn. Calculate mean values of x (x=count) for each date in the dataset where mean = the average c

[R] rollmean and stl

I need to investigate how rollmean and the trend returned from stl differ. I am trying to find out exactly what the trend part of stl is (I have just started coding in R and do not know fortran). I need to extract this because it will be used in further calculations, and it needs to be verified to

[R] rollmean()

Hello, I am trying to calculate a 31 day running mean in some temperature data along ROWS. Rollmean() works great along columns, but how do I perform this same action on my rows? The data is a matrix of 365 columns (days of the year) by 5,000 rows (lat/long coordinates). I would like to perform
