It is funny. I have to perform the approach of sediment fingerprinting for
my master thesis. Mr. Hasselman gave me the advice to take a closer look
into the limSolve package a few days ago.
I guess, the lsei-function of this package is exactly what you and i are
looking for. I have tried it out today and compared the lsei-results with
the results of the MS-Excel solver. They are the same!
You will find in the manual (Chemtax example), how to define the
constraints, that every unknown is >= 0 and the sum of unknowns is always 1.
Try to get familiar with the lsei-function and if you still need help, i can
send you my code.
Bearing the Monte-Carlo simulation in mind, the package could offer some
nice functions too.
Have a nice day and best regards
