One problem that I can see is that it seems like once a package bundle is installed, R basically has no knowledge that the packages belong to one bundle, other than the fact that the DESCRIPTION files of the packages have entries that indicate that they are part of a bundle. Are there ways to figure out such information other than checking packageDescription() of all installed packages?
No.
As from 2.1.0, install.packages() will install a bundle given the name of a package it contains (at least if the repositories supply the information), so there will be little need for users to know about bundles.
This is likely to be considered a kludgy approach, but one way of linking packages to bundles with a more global approach (as opposed to one package at at time) is the following:
There is code like that in new.packages. The problem is that looking at ca 500 packages is slow, especially on a laptop disc (or at least on the one of mine that has just died) but even on the fast RAIDs on our servers.

# Get the set of currently installed packages, taking # just the package and bundle names Pkgs.Installed <- installed.packages()[, c("Package", "Bundle")]
# Get the packages that are in bundles # "Bundle" will be NA if package is not in a bundle Pkgs.Installed[!is.na(Pkgs.Installed[, "Bundle"]), ]
On my system, where I have installed all CRAN packages that do not require third party libs, I get the following:
Pkgs.Installed[!is.na(Pkgs.Installed[, "Bundle"]), ]Package Bundle CoCo "CoCo" "CoCo" CoCoCg "CoCoCg" "CoCo" CoCoCore "CoCoCore" "CoCo" CoCoGraph "CoCoGraph" "CoCo" CoCoObjects "CoCoObjects" "CoCo" CoCoOldData "CoCoOldData" "CoCo" CoCoRaw "CoCoRaw" "CoCo" Greene "Greene" "Ecdat" Hayashi "Hayashi" "Ecdat" MASS "MASS" "VR" class "class" "VR" dse1 "dse1" "dse" dse2 "dse2" "dse" gdata "gdata" "gregmisc" gmodels "gmodels" "gregmisc" gplots "gplots" "gregmisc" gtools "gtools" "gregmisc" nnet "nnet" "VR" spatial "spatial" "VR" svDialogs "svDialogs" "SciViews" svGUI "svGUI" "SciViews" svIDE "svIDE" "SciViews" svIO "svIO" "SciViews" svMisc "svMisc" "SciViews" svSocket "svSocket" "SciViews" svViews "svViews" "SciViews" tframe "tframe" "dse"
One could then feasibly manipulate this information as one desires.
