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...
Thanks for your help,

S's plclust and R's hclust
...that Ward's method is not implemented for S's hclust whereas it is
implemented for R's hclust. What I would need is S's plclust and R's
hclust together, either in R or in S.
Many thanks to the ones who will help me solve that trick...

Boxcox transformation / homogeneity of variances
...p. 419) that the box-cox transformation can be extended to induce
homogenity of variances in conjunction with Bartlett's test of homogeneity
of variances. Does the Boxcox function implemented in R refer to this
extension ?
Thanks a lot,

pls.pcr compared to Unscrambler
...m the pls.pcr R-package developped by Wehrens with outputs from the Unscrambler software developped by CAMO company ?
I find very different outputs and wonder if this comes from differences between methods/algorithms SIMPLS (pls.pcr) and PLS1 (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
+
