If I understand you correctly, set the filter and use packageStatus().
Its summary() method tells you which packages you have installed which
are 'unavailable'. E.g. my Mac (with pkgType = "source") shows in
R-devel
summary(packageStatus(.libPaths()[1]))$Libs[[1]]$unavailable
[1] "BayesX" "EVER" "TSA" "akima" "degreenet" "difR"
[7] "ergm" "ff" "gam" "isa2" "latentnet" "locfit"
[13] "mapproj" "rtiff" "statnet" "tripack"

I only recently discovered options("available_packages_filters" = list(add =

2.10.0 or later] which goes nicely with my options("checkPackageLicense" =
TRUE) [new in R 2.11].
But now I want to purge my library of packages I would not have installed had
I known about this option earlier (I'm looking at you, "gam"!).
Short of erasing the whole directory of libraries and re-installing it, is
there an easy way of achieving this?
I could probably roll something based on tools:::analyze_license() but I
think the erase-and-reinstall option might be easier in this case :-)
