Hi Brian, If I have the stable water isotope composition of a soil layer and I want to now how rainfall events mix within this soil layers can I set...
Analyzing 2 isotope tracers in a source contribution study. When I run code to run the mixSIAR model, I get an error code for the code block "plot_prior(alpha.prior = 1,...
Hi Brian, Maybe it is simple, but unfortunately I cannot find any solution how to get posterior distribution values if I have two fixed factors. Wolfes example nicely present the...
Hello Brian and MixSIAR users, I am estimating diet proportions for an animal using two isotopes (13C and 15N) and 4 diet sources. Ideally, given the geography and biology of...
Dear Brian I am facing an "**Error in read.table(file=file, header=header, sep=sep, quote=quote :**" I have used these codes and the data file was saved in .csv format successfully. 1. library...
I need to trace nitrate sources and find the possible nitrate sources contributions to the groundwater through MixSIAR. I have tried to use the script of wolve example and modify...
Hello, I am trying to calculate endmember contributions using a single isotope case in MixSIAR. Then, I follow the code from this example and apply my data to do the...
Hello I am trying to run MixSiar by considering raw source data, using the values of end-members as date-specific. Accordingly, i ensured that both the source and the mixture files...
