| annotation_raster {ggplot2} | R Documentation |
<br /> This is a special version of geom_raster() optimised for static <br /> annotations that are the same in every panel. These annotations <br /> will not affect scales (i.e. the x and y axes will not grow to cover <br /> the range of the raster, and the raster must already have its own <br /> colours). This is useful for adding bitmap images.
