Checking package licences including dependencies?

Great, thanks.  I couldn't quite get your syntax to work, but

z <- packageStatus(.libPaths()[1])[[1]]
unname( z$Package[z$Status == "unavailable"] )

seems to do the trick for me.

Thanks again.

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

in R 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 :-)
