[R-sig-Geo] [FORGED] Modifying the length of a matrix variable

[r@i@1290 m@iii@g oii @im@com]

Hi Rolf (and others),

I tried your suggestion, but when I used dim(Model4.chopped), it still shows 95 layers, as shown below:
8192    95 
I also find that the total number of cells is rather low for that many layers. I started with 778240 cells over 95 layers.

Please keep the list in the set of recipients.  I am not your private 
consultant, and furthermore others on the list may be able to provide 
better advice than I.  I have CC-ed this message to the list.

To keep only "layers" 1 through 90 you could do:

    Model4.chopped <- Model4[,,1:90]

As I said before, it really is time that you learned something about R 
(e.g. by studying a tutorial).

cheers,

Rolf
