[BioC] Category package problems with Vignette documentation

[Robert Gentleman]

Hi Jean-Marc,
   You have not told us how you are getting your packages but I suspec 
that it is not using any of the tools provided by R. If you use 
install.packages (or for BioC reposTools and then install.packages2) all 
dependencies should be downloaded. If you choose to do this manually 
without using these tools, then you are going to have to sort the 
dependencies out yourself (and that seems to be most of what is 
happening here). Much of this is documented on the BioC website - I 
refer you there.
   A few more comments below.

  tools is a standard R package and comes with every copy of R, if you 
do not have it then you did something wrong at installation time.

R can only load packages you downloaded. There is no magic here, if you 
download 1.6.1 then that is what you have. If you want 1.6.2 you must 
download it (or as I said above please use the tools that have been 
written and documented).

  splines is a package that is distributed with R. Every copy of R has a 
copy of splines.

  Yes, but it would not help. Packages list only direct dependencies, 
other dependencies are determined by the direct dependencies. If you 
want to do manual installation, you are responsible for following the tree.

I have no idea what you are splines comes with R (it is a base package), 
you seem to have a very broken installation and can only suggest that 
you try to find out what has gone wrong and fix it.
