This argument was added to handle incompletely defined variables. From JAGS version 4.0.0, users may monitor variables that are not completely defined in the BUGS language description of the model, e.g. if y[i] is defined in a for loop starting from i=3 then y[1], y[2] are not defined. The user may still monitor variable y and the monitored values corresponding to y[1], y[2] will have value NA for all iterations in all chains. Most of the functions in the coda package cannot handle missing values so these variables are dropped by default.
Might be good to check all 'rjags' related functions for changes in arguments.
The current arg list is:
