Hi,
I'm working on a problem in which I'd like to interpolate a set of
oceanographic temperature profiles over a three-dimensional matrix of
unsampled x, y, & z locations based on a SpatialPointsDataFrame (WOD) in
which I've stored temperature data (WOD$TEMP) in association with
coordinate informa
Hi,
You can use writeGDAL() from the rgdal package.

?Thanks in advance. Using the package adehabitatHR for kernel analysis of bird
home ranges.
Looking for how to get a specific kernel, which is of class
SpatialPixelsDataFrame, into a format use-able by GIS platform, mostly QGIS, so
that I can work within specific kernels in the field.
Thanks
Whoops - somehow a double comma worked its way into the ."Call" lines
in the first patch I sent. The attached patch is updated to address
that issue.

Ran into a similar problem and was getting "Failure during raster IO" when
using extract on a very large raster with a small polygon. My solution was
to crop the large raster before doing the extract. Maybe this can help other
folks in the future. Cheers.

All fixed, thanks. I needed to install the "Spring Danceâ version of R. Not
quite sure what was wrong previously, but it works now!
Cheers

Dear List
I have encountered a problem with the extract function in Raster package,
previously it worked for me but not anymore. Here is an example from the Raster
package documentation. It does not work on my Mac OS X 10.9.3 running R version
3.0.2 (2013-09-25) -- "Frisbee Sailing (64 bit).

Thanks for respecting our guidelines - it is much harder to infect plain
text, which is why HTML is not welcome.

I have a SpatialLines(DataFrame) (e.g. streets) and SpatialPolygons(DataFrame)

package gstat offers simple 3D interpolation (idw, kriging), e.g.
library(gstat)
example(gstat3D)
and also spatio-temporal kriging; some memory limitations there may be
dealt with by using local kriging (see ?krigeST).
