modeltype = c('ranwalk', 'halfcauchy')

I get these warnings

2: In if (tolower(modeltype) == "sparta") { :
  the condition has length > 1 and only the first element will be used
3: In jags.samples(model, variable.names, n.iter, thin, type = "trace",  :
  Failed to set trace monitor for eta.p0
Variable eta.p0 not found

4: In jags.samples(model, variable.names, n.iter, thin, type = "trace",  :
  Failed to set trace monitor for eta.psi0
Variable eta.psi0 not found

[ ] Check all valid model formations
[ ] Identify ones where parameters are traced but don't exist
[ ] Remove the tracing of these parameters
