[R-sig-Geo] stack problem

[Amen Alyaari]

Hello All,

I have several rasters that I want to do some calculations ,basically 
calculating the moving average.

             dir2 <- list.files("D:\\2010+2011", "*.bin", full.names = 
TRUE)
            saf=stack(dir2)

code

           movi <-  overlay(stack(saf),fun=function(x) movingFun(x, 
fun=mean, n=3,  na.rm=TRUE))
              Error in .overlayList(x, fun = fun, filename = filename, 
...) :
          cannot use this formula, probably because it is not vectorized
  I then checked the data but found that all values were returned as NA 
and this may explain why I am getting the error.

when the files are stacked ,all in all are NAs

something is wrong because there is no NAs in my files. All  values are 
up to 9999. I wonder why this is happening, I checked the files 
separately(summary) and everything was right!as you can see bellow:

   I checked with only two files, but I got the same error:

               class       : RasterStack
         dimensions  : 720, 1440, 1036800, 2  (nrow, ncol, ncell, nlayers)
