[R] Interesting behavior of lm() with small, problematic data sets

I've recently come across the following results reported from the lm() function when applied to a particular type of admittedly difficult data. When working with small data sets (for instance 3 points) with the same response for different predicting variable, the resulting slope estimate is a r

Have you considered taking a random subset and plotting that? I'd bet you can get a really impression of the distribution with a few hundred thousand points at most. Tim Glover Senior Environmental Scientist - Geochemistry Geoscience Department Atlanta Area MACTEC Engineering and Consulting,

One additional option on the Linux-on-the-local-machine option described below. Consider running Microsoft's free virtual machine with a copy of Linux in there. Now you have the advantages of dual-boot with BOTH operating systems available with a toggle key sequence. Tim Glover Senior Envir
