R help - Jul 2010 - Checking package licences including dependencies?

I only recently discovered options("available_packages_filters" = 
list(add = TRUE, "license/FOSS")) [cf.
help("available.packages",
package="utils") 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 :-)

 What's the problem with gam? The ACM license on akima (on which it
depends) that requires permission/licensing for
commercial use?

Try this:

    License <- installed.packages()[, "License"]
    View(License)

and then just delete the ones you don't want or write a simple
function which examines License and issues a remove.packages() for
those that match or don't match whatever you want.

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"
