Hi Jeffrey,

For both the R interface and the MySQL interface, I get
   AVG(mycolumnA) COUNT(mycolumnA) mycolumnB
1          0.1717               99         1
2          0.0619              226         2
3          0.0353              312         3
4          0.0867              196         4
5          0.5119              379         5
6          0.4354              379         6
7          0.1286              140         7
8          0.2898              176         8
9          0.2667               75         9
10         0.4177               79        10
11         0.6667               96        11
12         0.0000                2        12


So it works but I get the following warnings :

Warning messages:
1: In mysqlDescribeFields(res, ...) :
  RS-DBI driver warning: (unknown type (246))
2: In mysqlDescribeFields(res, ...) :
  RS-DBI driver warning: (unknown type (246))

I do not test RMySQL on the 'older config' with R 2.7.2

What do you think? time to announce it on CRAN?
