I am doing some comparison for which I load both RMySQL and RPostgreSQL from my own packages TSMySQL and TSPostgreSQL and I am getting the following warning building a vignette. I think with package namespaces / S4 definitions it is a bit difficult to generate a self contained example, at least I have not yet managed to do that, but I would appreciate any suggestions about what needs to be done.
If someone else identifies your problem, great. Otherwise, have you tried creating a toy package containing only the minimum? If you get that to work, then I'd create a second toy package starting as a full copy of your existing package, then start throwing things out until you find the problem. I know that's a lot of work, but if you use a manual binary search technique (discard roughly half of the package at each step -- or discard first the 90% you think is least likely to contain the problem), it could go fairly fast. If you do it on R-Forge, then it's easy to give others access to your toy examples.
I hope someone else helps you fix this without the route I suggested. If not, I hope this helps. Spencer
Loading required package: TSPostgreSQL Loading required package: RPostgreSQL Warning in .simpleDuplicateClass(def, prev) : A specification for class "dbObjectId" in package 'RPostgreSQL' seems equivalent to one from package 'RMySQL' and is not turning on duplicate class definitions for this class (I'm using R version 2.15.1 on Ubuntu.)
