Hi R users,

I have been trying to install and use RMySQL on Windows98 for 
MySQL3.23.55-max using the pulldown menu. I am getting the following errors. 
I read the doc and some archived mails about a similar problem on unix like 
systems. Still can't get it to work. Some info below that may indicated where 
the problem is:
* The directory RMySQL\libs is empty---I was not expecting this.
* There is a file "README.windows" in RMySQL directory which suggests some 
changes using  the re-import utility "reimp", available at
This file is missing at this location. Instead there is a note stating that 
it is included in MinGW distribution. I installed this, but did not find this 
* Below is the info from the installation and loading the library:

> {a <- CRAN.packages()
+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a)}
