Very low importance, but I noticed this doesn't work.

library(raster)
r <- raster(volcano)
-r
# Error in -r : invalid argument to unary operator
0 - r ## is ok

Thanks for bringing that up and for the code suggestion. Fixed: 5e18157#commitcomment-31141037

I now get:

library(raster)
r <- raster(volcano)
-r
#class       : RasterLayer 
#dimensions  : 87, 61, 5307  (nrow, ncol, ncell)
#resolution  : 0.01639344, 0.01149425  (x, y)
#extent      : 0, 1, 0, 1  (xmin, xmax, ymin, ymax)
#coord. ref. : NA 
#data source : in memory
#names       : layer 
#values      : -195, -94  (min, max)
