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.
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've seen this with a vignette using both the maptools and trip packages, but it was just a warning and the vignette built just fine.
Yes, it is just a warning, and the vignette builds fine. It also looks like there is probably a simple fix to remove the problem that causes the warning, since that is what the warning suggests. However, as Spencer pointed out, isolating a simple example is not so easy. Paul
