Dear List,
I have a dataset (with an irregular grid) which I am trying to interpolate
to a regular grid with much higher spatial resolution using the autoKrige
function from the package 'automap'. But I get the error:
> SST_data <- autoKrige(SST~1, HG1990, center_points2, nmax=50)
[using ordinary
something like:
test1 <- extract(dryas,teow,na.rm=TRUE,sp=TRUE,fun=function(x) sum(x>0))
might give you what you ask: the area (count of raster cells, so in units
of cell areas) in each polygon of teow with raster values > 0.
If dryas has small cells, relative to the size of the ecoregion polyg

Hi.
I’m trying to develop a repeatable
process in R that I can use with a variety of data. Basically I'm trying to
join/merge/combine/intersect (I’m not sure technically which word is
right) a polygon and a raster so that I can do summaries on attributes from
both. I have A) a polygon shape file
Dear list,
We have a problem which appears to be a bug in either rgdal or raster,
although it could also be a bug in base R or in our understanding of how
to deal with connections.
We have a process which is writing a rather large (~10-20.000) number of
geoTiffs via writeRaster. However, the p

Try the osmar package: http://osmar.r-forge.r-project.org/.
The section "R as navigator" of their paper includes an useful example:
