Hi! I`m working with archaeological isotope data and I wanted to use the siarelicit function to introduce some priors. These priors are proportions I obtained by reading the literature of the archaeological site of how much of each food my consumers would have eaten.

The SIAR manual says I have to run siarmcmcdirichletv4 and then use the siarelicit(model1) function. The proportions must sum to 1 and the SIAR V4 Ecologist`s guide says that the first of it must be 0.7. Is this right? There isn`t such a prevalence in the components of the diet I`m working with. Can I still use this function if the proportions are, let’s say, 0,1; 0,2; 0,35 and  0,35?

Although what the manual says I ran siarelicit(model1) with my values and the program gave me the values to introduce in model(2) )
