Dear all,
I am reading a raster file using the readGDAL function. The file has 360x364
cells.
Looking at the structure of the object (class SpatialGridDataFrame) obtained
I can see:
@ coords : num [1:2, 1:2] 4081420 4092190 2955325 2966215
I need to transform it as SpatialPixelsDataFrame or d

Dear all,
I would like to plot 100 variograms on the same plot, possibly using a loop.
At the moment I am using autofitVariogram in the package Automap to fit the
variograms automatically.
I found some code calling the lattice package (
http://tolstoy.newcastle.edu.au/R/e7/help/09/06/0940.html), b
If you use:
# yum search proj
You should find proj, proj-devel, proj-epsg and proj-nad.
At least it is what yum just found from my computer now.
I had some problems earlier today to access fedora repository. What if you
change repository?

I did not find a way to store the simulation values in a dataframe. And I
did not find any example around.
I hope I manage to explain my problem.
Thank you very much in advance

Dear all,
I have a small image with three bands and I would like to normalise the
variance of the three bands in order to get a more homogeneous dataset for
further elaborations.
I am thinking to use the normal score transform, but I have some questions
about how to implement in R and especially ho
thank you. It seems now solved!

The kl <- kmeans(as(img, "data.frame")[1:3], 5) worked perfectly.
Thank you very much for the time spent to help me.

I am trying to do some clustering on images. And I have two main problems:
1) Clustering multiband images.
I managed to be successful with a single band image, but when trying to
apply to a 3 band I get the following warning message:

Dear list,
I managed to read an image in R and to make various elaborations on it,
mainly clustering. Now I would like to save the results I got as tiff or
geotiff.
I found a lot of different examples, but none seems to work.
Any suggestions on tutorials or code examples for saving clustering resul
