that's cool, I'm also interested in a similar problem but just with one
brick ending up with a slope raster as the output. It may be possible with
stackApply(). have a look. or maybe robert will chime in

Thanks Jacob,
I was unable to get ImageMagick working ( which saveMovie() relies upon..
as I recall ) so I had to live with the html animation.

Yes, I've done it and blogged about it a while ago.
I used raster a raster brick and then the animate package. For my own
project I made some changes to the animate package functions. ( the
functions currently switch directories under the cover of an API ) I don't
promote my blog on here cause it
Thanks Roger,
That appears to have cleared part of the problem up. And raster is back in
working order.
Now I have to recall how I got ncdf working on the MAC.

well, That didnt work.
I upgraded to R 2.12 and sure enough GDAL is broken. I downloaded the
latest framework
from KngChaos and did a standard install.
I tried the code provided here and Got the following

I would look at using the package 'zoo' your time series data would be a
zoo object
and then your date data would be coerced as well,
zoo, is very slick.

I Can take a look at it for you, if you want to work with gridded climate
data I would suggest raster.
You can visit my blog and I'll do my best to help you.

Guess I will wait for resolution to your issue since I use Kyngchaos

What is the format of the data?
if the file is in a standard format, please see the "raster" or "brick"
command
they will allow you to read direct from the file, with no trouble.
plot() just works as plot() is defined as a method for a raster layer and
for a brick if
you happen to have a multi ba
Elizabeth,
Are you using a raster stack or a raster brick?
i've written out 'bricks" successfully. Robert (maintainer) is Out of the
office for a bit
if you havent tried it using a brick, give that a go.

To get an idea about how mask works, see the following.

I like these suggestions as well
http://www1.maths.lth.se/help/R/RCC/
So for your function, combining the x and y coords into a single structure (
they are always paired so have a structure that reflects that )
dataToShape <- function( inputFileName, outputFileName, points, projection,
height)
I've been struggling with naming conventions as well.
having a style guide is important ( I say that now after having written way
too much
code without one)
Here's a start.. I bet there are other resources

I'm looking for some examples of how to read a NetCDF file with raster
directly. The manual is a bit
terse on the matter. The dats in question is a 3D (lon,lat,time) 72*36, 161
"bands"
On the MAC I get a request to load RNetCDF, which is not available in
Binary. I found a few mails
on geting RNetC
What kinda data are you working with? I can probably direct you to some
folks who can help, or you can join some of our discussions.

Assuming I have a matrix of Nrows and Mcols where
Column #1 is filled with a valid cell number for a raster. ALL cell numbers
will not
be present.
Subsequent columns (2-M) contain the data that I want to place in a sequence
of
layers, so that in the end I have a rasterStack of M layers. M can

I'm really looking forward to working with the package. Thanks ever so much.

On Cran it indicates that the package is not available on MAC (OSX 10.5.8)
Is that the whole story?
Is it a situation that will change or am I missing something. I've left a
similar Q on the Mac Sig, but havent got any feedback
