[R-sig-Geo] Recs for R tools that subset/tile raster bricks?

[Megan Maloney]

Hello all,

Does anyone know of a good R tool to subset/tile raster bricks?

I'd like to break a raster brick into smaller pieces to process. I'm
finding functions to subset or tile a single raster layer, but not for
multi-layer raster bricks.

The brick input is hyperspectral flightlines - very large, 1 m^2 resampling
covering a watershed, 340 layers. My code currently takes in a raster
brick, extracts values per cell, applies beta coefficients, and outputs a
nitrogen value to a raster.

I don't need the subsets/tiles to be a particular size or number, just
smaller. I was warned against dropping a whole flightline into R. I'm new to
R, so I'm not sure what limitations I'm running into except processing time.
All advice is welcome.

Thank you very much for your help.
Megan
