Maybe it is time to consult manual and help page for the function you use. 
For your convenience I coppied it below. I do not use the package so only 
few comments


siarmcmcdirichletv4(data, sources, corrections = 0, concdep = 0, 
iterations=200000, burnin=50000, howmany=Arguments

data A matrix with each food source as a seperate row and each isotope as 
a seperate
column.

^^^^^^^^^^^^^^^^^ most probably a numeric matrix

sources A matrix containing the mean and standard deviations of the 
fractionated correction
values for each of the isotopes. Also allows corrections = 0 for 
pre-corrected
data.

^^^^^^^^^^^^^^^^^ again a matrix (numeric) 

corrections A matrix containing the mean and standard deviations of the 
fractional correction
values for each of the isotopes. Also allows corrections = 0 for 
pre-corrected
data.

^^^^^^^^^^^^^^^^^^ and for the third time a numeric matrix

Only you know what are your data, sources and tef objects which you feed 
to the function. Why not to follow posting guide and uncover it to us, 
poor helpers.

Regards
Petr
