Dear community, I have been using ggplot2 for visualisation and I am really impressed by this. I do however have a problem that returns when plotting various types of spatial datasets as raster images. This is probably due to me not fully understanding the package.
When I am plotting images using geom_tile, I sometimes only have small dots in the image and at other times I have apparently blank images. On other occasions it works nicely without me being able to spot the differences between these plot requests nor the underlying data. I am usually plotting geophysical information either on a geographical grid (latitude/longitude) or on a map projection (normally using proj4 for the projection of data). I have tried to play with the position attribute, but without success so far, but believe that I suffer from some form of effect from this. I have tried to google for information and I have read the manual pages but so far without success. Do you have some suggested reading for problems like this? Is the problem likely to be related to position? I apologise for the vague description of the problem.
