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 composition of each ingredient in  
terms of fat, minerals, vitamins etc...
At this point the question, assuming that the procedure to create the  
product from the ingredients does not alter the chemical composition of  
any ingredient, is to determine the amount of each ingredient (milk,  
lactose, vegetable oil) in the final product.
Can anyone point me in the right direction?
Many thanks
