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:

# 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"

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.
