Hi. I have a shapefile. I guess because of cartography problem, the border of
some of the units that are supposed to be physically connected are 'snapped'
properly. As a result, when I use poly2nb, there are empty links.
I know I can set zero.policy=T in nb2listw. But I'm trying to use skater()
Hi Robert,
On my Mac the plot displays fine with no lines.

Perhaps the below works. It may be very slow if unq has many rows.
unq <- unique(as.matrix(data_stack))
fun <- function(x, ...) {
r <- rep(NA, nrow(x))
I see the same on Windows 7 64-bit, with 32-bit R and 64bit R.
There's no need for the transpose/flip btw:
image(volcano)
but raster graphics don't product it, so it's the underlying image C
code (which is rect under the hood)
image(volcano, useRaster = TRUE)
plot(0, xlim = c(0, 1), ylim = c(0
On my Linux system with 2.13.1 the R graphical display shows white lines.
If I generate/export a PNG using the png() function there are no white
lines.

When plotting a Raster* object, raster calls the 'image' function. spplot
uses 'levelplot'. Both are affected by these white lines in R 2.13.1 on
Windows, I think (anyone seeing this on Mac or Linux? or not seein

You are plotting longitude/latitude data on an map with Albers projection.

Ah-ha,
NA's are the cells outside my mask.
Lines appear to be a GUI issue, went back to 2.13.0 and plot of raster looks
fine.

@SM - I am in fact using 2.13.1 and will look into the image() call. The code
should be attached, here it is again

Hi,
please post code to replicate the problem.
also include sessionInfo().
how are you plotting the raster, are you using 2.13.1? ( there was a bug
report that looks somewhat like yours
on that today using the image() call.
More details and we can help.
Thanks

Hello there,
I'm using "raster" to great effect in a little something I'm building, but
having a time trying to figure out this current issue. My intent is to build a
"distance raster" from a center point out to 1km with cell size of 30x30. I had
a few runs yesterday where this worked, but toda
The error message is an indication that you're predicting (kriging) with
a singular covariance matrix. The most frequent reasons for this are
duplicate observations [1] or perfect correlation in the
coregionalization model [2]. For [1], see ?remove.duplicates, for [2]
see argument correct.diagonal

If I want to use ocean data (for example- Sea Surface Temperature,

Hi all,
i am trying to use categorical kriging for prediction of soil classes in an
area. I am pretty new to using cat. kriging in R soI probably am making some
beginers mistakes. Attached is a reproducable sample with sample data.
When i try to use predict() i geta n error- I am pretty
