Greg,
I'm quite certain that kriging would not be appropriate with model
output--you won't have any errors to produce the necessary statistics.
Are you looking at smooth terrain (e.g., over the ocean) where topographic
influences are negligible and you may want to interpolate the pressure

This reply is a little late, but after much searching, I cannot find an R
package/function that fits my needs.
I am trying to perform either bilinear or bicubic interpolation using great
circle distances (ie using a spherical model of the earth). Here is what I
have tried:

It is not the paste function (as has been mentioned before), but the print
function that is doing different things. The default behavior for printing
character strings is to put "" around each string, if there is a " inside the
string, then the print function will put the \ in the representatio
Hi Ned, that is the downside of using a package under development
(albeit *quite* stable now).
"x <- setRaster(x)" has been replaced by the (generic) "x <- raster(x)"
"x <- setDatatype(x, value)" has been replaced by "dataType(x) <- value"
As for the versions, you are not doing anything wrong. It

I just updated my R installation to 2.9 and then updated my packages. It
looks like setRaster and setDatatype are not included in the Raster

the Raster package that version 8.9-14 is the most current version but

Hi Roger,
Thanks for the response. Unfortunately, I'm still getting the same error
running predict.sarlm ("Error in if (nrow(newdata) !=
length(listw$neighbours)) stop("mismatch between newdata and spatial
weights") : argument is of length zero").
Thank you, Edzer.
My second question bas been solved by using:
proj4string(pred.mud.ked) <- CRS("+proj=longlat +datum=WGS84")
For the first question, I have checked ?levelplot, but found no clue to do what
I intended. Thanks for any further help.
Cheers,
Jin
