Replace missing values in spatial design using moving average
...issing values in the z column and I would like to replace them with an optimized estimation from the neighbour cells. I could not find any function in R to do that. Is anybody aware of such function ? Maybe someone knows how to implement the Papadakis method in R...

pls.pcr compared to Unscrambler

Strange problem.
Hi, everyone, I am a new user of R. Recently, I tried the following commands, but couldn't make them work. If any one of you has some ideas about it, please help me. The commands are >std<-1000 >mean<-8000 >prior<-function(n){1/(sqrt(2*pi)*std)*exp(-1.0*(n-mean)^2/(2*std^2))} >plot(prior,1,15000) >post<-function(n){ + if(n < 9543) + 0 + else + prior(n)/n +
