Hi Lyndon,
I think there is a function for that:
x <- stackSelect(rb2, ind.r)
I.e., for each cell, use the value in ind.r to select the layer in rb2 from
which to take the value for the output layer.
Best, Robert

Dear List,
I was hoping to get some advice on the best way to solve the following
problem given two raster bricks.
Given two bricks:
r.list <- lapply(1:20, function(x) {
r <- raster(xmn = 25, xmx = 32, ymn = -34, ymx = -27)
res(r) <- 0.1
r[] <- runif(ncell(r))
return(r)
})
rs1 <- stack(lappl
Ok ok, thanks to all!
The "lazy" was me! The server admin updated R and packages two days
ago, but not me!
R version on my Windows C is
R version 2.13.1 (2011-07-08)
and sp version
Package: sp
Version: 0.9-88
Date: 2011-09-14
I haven't access to server now, but I took note and I will run i

This is what we call a reproducible example:

David,
Can you provide a reproducible example, perhaps based on the below (from
?interpolate), but then mimicking what you are doing?
Robert
library(gstat)
library(raster)
r <- raster(system.file("external/test.grd", package="raster"))
data(meuse)
mg <- gstat(id = "zinc", formula = zinc~1, locatio

A reproducible example and the basis system information requested
in the posting guide would be very helpful.
OS, version of R, versions of the relevant packages...
We really do need this information to answer questions.

Ok, I’m sorry. I think that there was a little problem with my previous
message.
I’m trying to execute some R commands on a linux server (where I
installed R and packages previously) to create a SpatialGridDataFrame.
It has to be a grid 10*10 to which I will associate data resulting from
simu

Hi Matilde,
Your short and cryptic mail leaves us guessing what is going wrong here.
Please provide more info, see the R-help posting guide for some advice
[1]. Most important is a small piece of R code which reproduces this
problem.

Hi,
Im trying to apply a gstat model that incorporates an external drift
variable to a raster, using the interpolate function of the raster
package. I seem to be having trouble making it use the values of the
raster layer as the covariate specified in the gstat formula. Any help
greatly appreciate
Hello all,
I'm trying to execute a very simple command on a linux
server:
Locus1grid as asMethod -> as asMethod
Execution halted
Could you help me? May be the sspdep package doesn't work in the same
way if working on a server? I admit that my experience working with
servers is almost 0!!
