jg_vnodes: Get variable nodes in JAGS model code

In poissonconsulting/jaggernaut: Bayesian Analyses using 'JAGS'

Description

Gets names of variable (as opposed to constant) named nodes in JAGS model code

Usage

jg_vnodes(x, type = "both", indices = FALSE, comment = "[$][^\n]+[$]")

Arguments

x	string of JAGS model code
type	string of node type. Must be 'stochastic', 'deterministic' or 'both' (the default). A variable node is any word possibly
indices	flag of whether to retain indices
comment	A string defining the regular expression to use to filter text from the comment for the node.

Value

Character vector of unique sorted variable node names

Examples

model_code <- "data{
   Y ~ dpois(2) 
}

model {

 bLambda ~ dlnorm(0,10^-2) #$\\lamda_{beta}$
 for (i in 1:length(x)) { x[i]~dpois(bLambda) 
   b[i] ~dpois(1)
   bc[i] <- b[i]
 }
 bd <- dpois(1, 1)
}"
jg_vnodes(model_code)
