[R-sig-Geo] grid.text with rasterVis::layerplot

Below is a chunk of code that plots a rasterStack with 6 layers; I am trying to put labels a-f in the bottom right corner of each plot. The code below only shows the letter “a”, how do I get different letters to show in the bottom left corner of each of the 6 plots as I use levelplot?

[R-sig-Geo] Regional Average of Rasters

I have a rasterBrick (temp) with global temperatures, and a rasterLayer (regions) of global regions. I would like to create a rasterBrick of regional average temperatures. So far I have the following: region1-mask(temp,regions,maskvalue=1,inverse=TRUE) mean1-cellStats(region1,mean)

Re: [R-sig-Geo] Aggregate using Shapefile

polygon. See the examples. Alternatively, you can use rasterize and then use crosstab. Robert On Fri, Mar 22, 2013 at 10:13 AM, Tiffany Smith smithtiffa...@gmail.com wrote: Hi all, I'm looking to use a shapefile to aggregate a raster layer. Here's what I have so far: indexAL-raster

[R-sig-Geo] Aggregate using Shapefile

Hi all, I'm looking to use a shapefile to aggregate a raster layer. Here's what I have so far: indexAL-raster(myfile.nc) ALshp-readShapePoly(ALzipcodes.shp) ALrst-rasterize(ALshp,indexAL,fun=mean) indexAL has a finer resolution than ALrst, and I'd like to aggregate indexAL up to the scale of

[R-sig-Geo] Writing Raster values to .txt file

Hello, I'm trying to write out the values of a RasterBrick to a .txt file. Here's what I have: b-brick(file1.nc) vals-getValues(b) write.table(vals,file1.txt) Where 'b' is a RasterBrick with dimensions [224,464,33] which corresponds to [lat,lon,time]. The output, 'vals' has dimensions
