...lly-adaptable phone? Here are some of my thoughts. This is not anything I plan to do soon (if at all), but I really find it strange that there aren't such phones already. == Small Quantities: When you look at such systems it becomes aparant that you can get much nicer prices if you buy large quanities. But this is something that will be a problem. Not only for prototying. The fact that you're limited to a strict hardware setting is very limiting. No mixing and matching like in a standard PC. I'm not exactly sure how to overcome that. == Platforms: There are many embedded platforms now...

In my (limited) experience R is more powerful concerning data manipulation. An example: I have a vector holding a user id. Some user ids can appear more than once. Doing SELECT COUNT(DISTINCT userid) on MySQL will take approx. 15 min. Doing length(unique(userid)) will take (almost) no time... So I think the other way round will serve best: Do everything in R and avoid using SQL on the database...

The other thing this merge helper

Greetings, Can anyone relate experience(s) installing CentOS on Compaq rack mount servers units please?

Let me know in terms of CentOS 3 and/or 4 please.

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML
