Specifying Packages For Dependency Graph Creation With R

Question

[Jamie]

I want to grab select packages from the Bioconductor repository index. As I understand it, there are one of two ways to do this:

1. Use some argument with the following repository url:

   repos = biocinstallRepos()[1]

2. Use some extra argument to the makeDepGraph function below:

   z = makeDepGraph(repos)

How can I specify - by name - for which packages I want to create a dependency graph?

Also, using Rgraphviz, how can I add the name of each package as a label?

TIA.

For your first question, take a look at the subGraph function from the graph package. For your second, please take a look at the Rgraphviz vignette.
