Removing cran mirrors
Note that with such a policy, half CRAN packages wouldn't work anymore, because then we'd had "cut off" several packages away that are dependencies for others etc. Examples for packages we probably should "cut off" now (since they already caused too much time looking at them) are: ? clusterfly, ggplot2, lvplot, plyr all of them giving WARNINGS under R-2.10.0 and I guess you know the miantiner who has been asked by automatical notification to fix the issues.
Hopefully this doesn't sound too self-serving, but: * Keeping a mirror up-to-date is _much_ easier than keeping a package up-to-date (i.e. you just have to run rsync regularly). * I don't recall receiving any automated notices about problems, and I've just tried searching for combinations of R 2.10, warning and ggplot2 as well as several other attempts and haven't been able to find anything. I normally try and keep on top of issues like this. Hadley
