Hello Milton,
thanks for that beautiful R-hack !
Since I am working on a minimal "bread and butter" machine I went for Moritz'
solution but it's a neat idea to use R for the task.
Eventually, GIS-hacking should become part of the Olympics and you all should
try to get medals :-)
Actually, I stand corrected. Daniel was right: v.reclass does allow
character columns and v.dissolve, therefore, does as well. I just tested
with a map as it works with current svn trunk and and old pre-release 6.3:
> v.info -c NUTS2_2006
Displaying column types/names for database connection of layer 1:
INTEGER|cat
INTEGER|objectid
CHARACTER|cntr_code
INTEGER|stat_levl_
CHARACTER|nuts_id
DOUBLE PRECISION|shape_leng
DOUBLE PRECISION|shape_area
> v.dissolve in=NUTS2_2006 col=cntr_code out=countries
And I get a nice countries map...
So your error message is a bug:
results in dbmi: Protocol error ERROR: Cannot open select cursor:
>> SELECT cat, FIPS_1 FROM counties ORDER BY FIPS_1 ERROR: Unable to

Could you post the output of 'v.info -c counties' ?
