[Bioc-devel] Installation process for affymetrix databases (*.db packages)
Hi Auke, Thanks to Martins generous hint, I think I have this fixed. There were some default behaviors in a package we depend on that were opening these databases so that they could be written to (even though nothing was being written there). If you grab the very latest version of AnnotationDbi, you can try to see if its working any better for you. The latest version is already available in the svn repository, but you should be able to get the latest tarball from our website/build system within the next 24 hours or so. Marc

Hi Auke,
Hi Marc,
The installer should place the contents of "inst/extdata" into "extdata"
of your installed library, but that is about it. There *IS* a
dependency however that is logged in the DESCRIPTION file. Each chip
package requires that an "org" package be installed in order for it to
work. So for example, this package "zebrafish.db_2.4.1.tar.gz "
requires the "org.Dr.eg.db". And the message below seems to be
complaining that the database in "org.Dr.eg.db" is not available. It
does not need to write to this DB, but it does need to be able to read
it. Did you install the org packages and other dependencies 1st?
I most definitely have that package installed. The package manager resolves all dependencies. As far as I'm concerned, the error is pretty clear: something's trying to open a file with write permissions, and that's prohibited. Could it be that the org.Dr.eg.db is opened with write permissions, even though nothing is really written? If so, could that be fixed or will I need a workaround?
Also is there a specific reason why is biocLite() is not your preferred
way to install bioconductor packages? It handles all of these issues
for you and installs requested packages (and resolves dependencies).
No, there is no specific reason for me not to use biocLite, but then again, I personally don't seek anything in Bioconductor at all. I'm working on enabling virtually all users of Gentoo Linux to install CRAN and Bioconductor packages using their regular package manager, which I think offers some obvious conceptual advantages. Perhaps one of the bigger issues with biocLite() some Gentoo purists may have is that it installs files without the package manager knowing anything about those files, and some users consider that evil. Another serious advantage would be dependency resolution for external packages, like for CRAN's gsl package, but I have yet to find a package with external dependencies in Bioconductor.
Yes, I've seen that, and I've actually scavenged the (two) repository locations by reading biocLite() and friends :-) So, to sum it up, could it be that the database is opened with write permissions, but nothing is actually written, and is it possible at all to fix this, or is this inherent in the way R reads sqlite databases? Thanks again, Auke Booij / tulcod.
