SIAR problem with model running
...rophic enrichment factor table (columns include source, mean15N, SD
d15N, mean d13C, SD d13C)
I've read the tables in as .txt ('data' for consumer data, 'sources' for
source data, and 'tef' for trophic enrichment factor) and tried to run the
MCMC as follows:
model1<-siarmcmcdirichletv4(data, sources, tef, concdep=0, 500000, 50000)
I keep receiving the following error warning:
'Error in siarmcmcdirichletv4(data, sources, tef, concdep = 0, 5e+05,
50000): NAs in foreign function call (arg 5)'
there aren't any NAs in my data set, so I assume that NAs are being created...

siar error
...e example script and example data supplied I cannot get 1) the model to
run unless I specify iterations =500 and burnin = 500 and 2) if the model
does work without crashing R then the function "siarhistograms" does not
work . Can anyone point out where I am going wrong?
>model1 <- siarmcmcdirichletv4(consumers, sources, corrections,
concdep=0,iterations=500,burnin=500)
>siarhistograms(model1)
>Producing plot.....
>Error in plot.window(...) : need finite 'ylim' values
Many thanks.
