How to get the rolling standard deviation in rasters?
...hown below.
I read this documentation of R movingFun and found that sd was mentioned at
http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/raster/html/movingFun.html
I wonder if needs any other things to conseder or sd is not at all supplied
by this function.
sami<- list.files("C:\\Usersfinal-2010", "*.envi", full.names = TRUE)
saf=stack(sami)
dm <- overlay(saf ,fun=function(x) movingFun(x, fun=mean, n=3,
na.rm=TRUE,fill=NA))
### worked very well
ds <- overlay(saf ,fun=function(x) movingFun(x, fun= sd, n=3,
na.rm=TRUE))
### did not work...
