Most R packages are developed & maintained by a single scientist in academia or industry, and survive by the thin thread of that person's continued interest. Whereas vanilla R will be with us now and forever. So there's some risk to relying too heavily on packages To alter Tom's remarks a bit, it's like deciding not to use 'slang' words because they come & go In any case, enough blathering; let's all set to trying out hand at real world problems, however plain or fancy the approach, in the coming week, and see if we can reach critical mass for common improvement SW
