Hi Hadley, That would great if rasters could be printed more efficiently. Could you send me an e-mail, or post on the r-sig-geo list when you are ready to receive any contributed code? Paul On 12/15/2010 10:20 PM, Hadley Wickham wrote: This is something that I hope the student would explore

I'd love to see a separate, dedicated package bringing spatial functionalities to ggplot2 - this is such a great tool. However, it seems to me that a significant problem when using ggplot2 is the lack of geom dedicated to raster data. My experience is you can't really deal with big rasters using g

I think both packages have good reasons to not want to depend on eachother, as integrating this in one of them would imply. Your solution seems a reasonable one to me. On 12/15/2010 02:07 PM, Hadley Wickham wrote: > I have a student who is interested in working on more spatial features > for ggplo

I have a student who is interested in working on more spatial features for ggplot2 this summer. That work is likely to involve separating out all spatial features from ggplot2 into their own package and that would be a good place for this. Hadley On Wednesday, December 15, 2010, Paul Hiemstra wr

Hi people, I posted a similar question to the ggplot2 mailing list and with their help and a lot of tinkering I got a well working function to add a scalebar to a ggplot plot. I could add the function to automap, but is there another package which would be more appropraite, e.g. sp (Roger?)?
