comment Running a Python Script to Extract Raster Data in QGIS
@BenThompson - are you using R? I can't remember off-hand but quite awhile. My rasters weren't anywhere near as big as yours (only 10MB) so that will probably slow things down a lot.

@underdark - yes I'm pretty sure I'm using the right one. I can only see one raster calculator in QGIS 1.8 and the picture of the GUI in the documentation is the same. Most of the commands work just not the conditional statements.

thanks for the suggestion but I've already tried saga - the results it produced were inconsistent i.e. doing the same thing twice gave different results. I know the ZonalStats plugin in QGIS works, hence I'm after a way to automate ZonalStats.

@Curlew - having a play with your plugin. Looks great but can't get it working. Every time I try to run landcover polygon overlay function I get an error : replicamag.co.uk/error_msg.txt

@Curlew - Your R script does indeed work, thank you. The only thing I've yet to work out is how to append the results returned in R to the .dbf file for my shapefiles (any help with this would be much appreciated).

@Curlew - Sylvester's method, while it sounds very good, would represent a massive learning curve for me and I don't have time to do this at the moment. I appreciate Sylvester's help but it wasn't the straightforward answer I was after. I though I had most of the code I was after in the post I mentioned in my other question (gis.stackexchange.com/questions/23203/…). If Sylvester's method is the only way to do this in python maybe I underestimated how difficult it would be.

Chad - yes it's a similar question but its more specific. No one has answered the other question, instead they suggested other ways of solving the problem. I don't know how to delete the other post
