Dear List,
I am trying to calculate
*GLCM textures of all bands of a raster stack using GLCM package. Using
following code it runs perfectly. The code created four stacks for each
bands, each stack contains for 8 raster objects, but I am facing
difficulty to get results for further
a bell.
Thank you once again,
Iain

You can add following line to get a map without

A better way is use create a list of variables, so i will assume
the name of the variable.

Is there anyway to calculate population weighted centroids of a spatial
polygon in R? Any idea will be appreciated. Thanks

I am trying to calculating 95th percentile within polygons from a of
set realizations - something like zonal statistics.
How do I calculate 95 th percentile for each polygon over all realizations.
Thanks
Zia
For example:
data(meuse)
data(meuse.grid)
coordinates(meuse) - ~x+y
percentile.
These are two different things. The first is a spatial aggregation,
the second an aggregation over the (sampled) probability distribution.

I used following code to merge a series of shape files with similar
file structure. We can try this, but you need to do some modification of
the code.

Hi,
I am trying to do kriging with in strata. I use the example in book
Applied Spatial Data Analysis with R page:217. It works fine with
meuse data. But when I am trying to use my data it shows some error
massage.
Do I missing something here?
Thanks in advance
Zia
