my RMySQL connections are so SLOW
Hi all,
I'm using the latest RMySQL to send requests to a MySQL database (which
is quite small for the time - let's say 20 tables with a total of 1000
rows), and this should be part of a whole decisionnal system. It
produces results which are displayed on a website, and therefore I need
fast results (the database being quite small, I think this must be
possible !).
Unfortunately, a

RMySQL load error
I'm having trouble getting RMySQL to load. I was able to build it and install
it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37.
I've read many postings about this but have not found a mention of my
particular problem (some closely related). I get the "unable to load shared
library, no such file" error, but all the files do exist, RMySQL.so and

DBI / MySQL problems

S4 coercion responsibility
Should functions or the user be responsible for coercing an S4 object
argument containing the proper object (and thus should below be
considered a bug in the packages or not)?
The example is with RSQLite but the same thing happens with RMySQL, and
other DBI packages.

S4 coerce
(I am not sure if this is a bug or a request for a more understandable
warning, or possible something obvious I should be posting on r-help.)
I am trying to coerce an new class object to be a DBIConnection and it
does not work the way I think it should:

Can you create a MySQL database with RMySQL?
Is it possible to create a database in MySQL via RMySQL?
Also, is the format for the authorization field
'userName/password at databasename'? I saw an example like this somewhere
in the documenation, but I haven't found the actual specification.
Thanks,

Here's the error.

RMySQL CREATE TABLE error
Hi all-
I am stumped. The code in A. returns errors at lines 14 and 15 and fails
to load series1 and series2. However, in B., if temp1 and temp2 are
called again (which returns a "Table exists" error; see lines 14-17 in
B.) series1 and series2 load correctly. Any ideas? Also-I am open to any
suggestions to improve the code as I am a horrific programmer. Thanks

Why is bubbles() creating empty png graphs?
This code below produces empty XXX.png files - if I use plot(), it works
and if I enter the commands
png(filename=fn)
bubble(positions, do.sqrt=FALSE, main=q)
dev.off()
manually, it works as well.
I am lost - any help appreciated.
The weird thing is that it worked before I made some changes... (I don't
have a copy of the working version...).

Problems with RMySQL and MySQL server version 5.1
For those R user's who don't subscribe to R-sig-db and are having
troubles with the latest RMySQL binary on CRAN, please read the email

RMySQL 0.7-2 does work with MySQL 5.1, however the CRAN binary is linked
against the 5.0 version.
