...nse terms. I can not assume a specific number of columns in the data.frame; might be 3, might be 20. My central problem is that the formula given to lm() is different each time. For example, say a data.frame had columns with the following headings: height, weight, BP (blood pressure), and Cals (calorie intake per time frame). In that case, I'd need something like the following: lm(height ~ weight + BP + Cals) lm(height ~ weight + BP) lm(height ~ weight + Cals) lm(height ~ BP + Cals) lm(weight ~ height + BP) lm(weight ~ height + Cals) etc. In general, I'll have to read the heade...

Ran across a new iPhone app on the the App Store today. It is called DrinkFit and gives you nutritional facts for Beers, Wine Coolers, Cocktails, Liquor, Wine and Mixers. It's pretty cool, gives you calories, carbs etc... for all your favorite drinks so if you are at a bar and want to make a smarter choice, it's a pretty good reference. Check it out on iTunes and www.drinkfitapp.com

Dear All, I hope this is not too off-topic. Essentially, I need to know if there is any R package which can help me with a deformulation project. Suppose e.g. that you know from a chemical analysis the fat, mineral, vitamin, energy [and so on] content of a certain food product. You also know the ingredients of this product (e.g. milk, lactose, vegetable oil) and you know the chemical
