Users of R 2.11.1 (let alone 2.11.0) x64 Windows were asked to update
in August, and we switched off the last remnants of support when
2.12.0 was released.
Please do as the posting guide asked you to do before posting: update
to R 2.12.0 (or 2.12.0 patched), and update all your packages.
lattics is 0.19-13
raster is 1.6-15
sp is 0.9-72

Hi Joshua,
OK, my session info is this:

These are not the same versions as below.
loaded via a namespace (and not attached):
[1] grid_2.11.0 lattice_0.18-8
I also have installed the 32 bit version of R under windows 64 bit
and there the raster package has the function extract and session
info is:
R version 2.11.0 (2010-04-22)
i386-pc-mingw32

attached base packages:

other attached packages:
[1] raster_1.6-10 sp_0.9-62
loaded via a namespace (and not attached):
[1] grid_2.11.0 lattice_0.18-5
Obviously i would like to work with the R64 bit because i have more
memory available. It is not clear to me why the function extract
exists in the package raster for 32 bit but not for 64 bit. Is there
any reason?
Thanks,
Monica

Hi Monica,
Evidently, there is not an "extract" function in your search path
(base R, loaded packages, etc.). Given that you are talking about a
function from a package (rather than base R), it would probably help
us more if you mentioned what version of raster you have installed.
You can get this easily by loading it and reporting the results of
sessionInfo() (per the posting guide). On my current system (see
specs below), there is an extract function and it seems to work.,
Cheers,
Josh

Hi,
I would like to use the function "extract" from package raster and i get the
following error:
m01e <- extract(marsh01, p)
Error: could not find function "extract"
marsh01 is a raster object and p is an intersectExtent object that is not null.
The package is installed and loaded, i use a Windows machine 64 bit and R x64
2.11.0. Do i really need to update my R to use this function?
Thanks, Monica
