Dear all, I took a while to 'solve' the following problem. I need to use both RdbiPgSQL and geneplotter. The latter loads, directly or indirectly, all of annotate AnnotationDbi DBI RSQLite xtable lattice I used to have an old version of annotate that I didn't bother upgrading and worked fine. I recently did however, resulting in the indirect loading of DBI. This, in turn, is incompatible with Rdbi, resulting in connection errors: Error in function (classes, fdef, mtable) : unable to find an inherited method for function "dbConnect", for signature "PgSQL" I solved it by first library()-ing DBI, then Rdbi and RdbiPgSQL. However, I don't think this is very satisfactory. The ordering of libary() statements should be irrelevant and secondly, if I would just like to plot a few genes, it is overkill to also load complete database connection code. Would a dependency "Suggests: DBI etc." , rather than "Depends: DBI etc." not be more than enough for the annotate package?

No. Since BioC2.3 all annotation packages are based on RSQLite databases, so annotate requires DBI to be loaded in order to work correctly. You are correct that this is an unsatisfactory situation, and namespaces are supposed to alleviate function masking, but only if they are set up correctly. So you should be contacting the maintainer of RdbiPgSQL directly (Hi Jianhua!) and asking him to fix his package. HOWEVER, you are using a dirt-old version of R and BioC, and Jianhua may have fixed this problem many months ago, so you need to upgrade to R-2.9.0 and BioC2.4 first, to ensure this problem still exists.

Hi Philip, Please upgrade to R 2.9.x and relevant packages. We are not able to support older versions. We will have a look at this issue in the 2.9.x suite, but will not provide any patches for older versions of R/BioC. Also, you are mixing new versions of packages with old versions of R. We have specifically asked that users not do that, and if you do do that, please do not report any bugs. We are not able to provide assistance for people that do not follow the guidelines. best wishes Robert Philip Lijnzaad wrote: >> I need to use both >> RdbiPgSQL and geneplotter. > > Sorry, just to be complete, this is R 2.7.1, all packages all at their latest > version: > > package.version("geneplotter") => "1.22.0" > package.version("Rdbi") => "1.8.0" > package.version("RdbiPgSQL") => "1.18.0" > package.version("DBI") => "0.2-4" > > Regards, > > Ph. > -- Robert Gentleman, PhD Program in Computational Biology Division of Public Health Sciences Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N, M1-B514 PO Box 19024 Seattle, Washington 98109-1024 206-667-7700 rgentlem at fhcrc.org

I am sorry that I forgot to mention that I had actually tested it there as well, and the issue is identical (see below). ?I had to downgrade to a previous release because RdbiPgSQL is broken in 2.9.x (see thread 'RdbiPgSQL problem: SET_VECTOR_ELT() can only be applied to a 'list', not a 'character').

At the same time (since this basically is caused by the database connection package being broken), I would (kindly!) suggest that, in an ideal world, RdbiPgSQL ought to have been tested more thoroughly (especially connecting with an actual database) before the release; after all this is an infrastructure package.

It's unlikely to be the case since PgSQL() is defined as: PgSQL <- function() { out <- list(description = "PostgreSQL object") class(out) <- c("PgSQL", "Rdbi") return(out) } >> conn=dbConnect(PgSQL(), host=db.host, dbname=db.name, user=db.user, > password=db.password) > Error in function (classes, fdef, mtable) : > unable to find an inherited method for function "dbConnect", for > signature "PgSQL" There are 2 dbConnect() generic functions: one is defined in DBI and the other in Rdbi. Roughly speaking DBI and Rdbi are 2 incompatible infrastructure packages on top of which R interfaces to specific RDBMS can be written. The current DBI and Rdbi families include: - RSQLite, RMySQL, RPostgreSQL, ROracle for the DBI family. - RdbiPgSQL (and maybe others that I'm not aware of) for the Rdbi family. Rdbi existed before DBI but is obsolete now. We have kept Rdbi + RdbiPgSQL in Bioconductor so far only because the DBI family was lacking an interface for PostgreSQL. But now that RPostgreSQL is here (released in last October, available on CRAN), there is no reason for anybody to keep using Rdbi + RdbiPgSQL. So our plan is to deprecate them soon (after we've done enough testing of the new RPostgreSQL package). In the mean time, the right way to deal with this name clashing is to use fully-qualified names: conn <- Rdbi::dbConnect(PgSQL(), ...)
