Error in model compiling using RJAGS package
The problem is that the weekday
variable from the RailTrail
data is logical, with values {FALSE
, TRUE
} which have numerical values of 0 and 1, respectively. You need to turn those into values 1 and 2. This should do the trick:
poisson_jags <- jags.model(textConnection(poisson_model),
data = list(Y = RailTrail$volume,
X = as.numeric(RailTrail$weekday)+1,
Z = RailTrail$hightemp),
inits = list(.RNG.name = "base::Wichmann-Hill",
.RNG.seed = 10))
