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

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

SUCCESS! Thank you so, so much, Stephen! Indeed, that worked out well, and dim(subset) shows:
64   128    90
I am very, very grateful for this! Thanks to the others, too, for their assistance with this!

The last few messages provided important information which was previously absent. Try:

subset = Model4[[1:90]] 

This will subset the brick to layers 1 through 90.

I would also suggest some further reading around the raster package and NetCDF files (e.g. the ncdf4 package) would be useful to you.

I know nothing about rasters, the brick() function, or the raster 
package, so include me out at this stage.

Others on the list may be able to help you.  Particular if you can force 
yourself to ask a *focussed* question.

cheers,
