Hi,
Whenever I have a MySQL query that returns a Decimal result to R I get
the following warning in R:
Warning message:
RS-DBI driver warning: (unrecognized MySQL field type 246 in column 1)
I get this for a simple query like "SELECT 2, 2.5" !!
I am using:
R ver 2.1.1
RMySQL ver. 0.5-7
DBI ver. 0.1-10
MySQL Ver 14.12 Distrib 5.0.18.
Please Help!

Extending data frame with longer columns
Hi,
I am a beginner in R and have only read a few chapters in the R book,
I was not able to find a solution for this simple problem.
I have an empty data frame:
a=data.frame(name="test")
which I would like to extend in a for-loop (with data extracted from a
database). Ideally I would like to extend the data frame like this:
a["new_1"] = 1:10
a["new_1"] = 1:12
