Good. In the meanwhile I have put together a rewrite of the example in
the jags documentation as a stylistic statement. Consider using using
Python variables and call R functions through their Python
representation: it makes the code easier to read for Python programmers
without an R background.
from rpy2.robjects.vectors import FloatVector, StrVector
from rpy2.robjects import r, globalenv
from rpy2.robjects.packages import importr
base = importr('base')
r2jags = importr('R2jags')
# An example model file is given in:
model_file = base.system_file("model", "schools.txt", package="R2jags")
# data
J = 8.0
y = FloatVector((28.4,7.9,-2.8,6.8,-0.6,0.6,18.0,12.2))
sd = FloatVector((14.9,10.2,16.3,11.0,9.4,11.4,10.4,17.6))
# using a separate environment might be cleaner and evaluate the call
# in that environment might be cleaner, but let's keep it simple
globalenv['J'] = J
globalenv['y'] = y
globalenv['sd'] = sd
jags_data = StrVector(("y","sd","J"))
jags_params = StrVector(("mu","sigma","theta"))
jags_inits = r('''function(){
list("mu"=rnorm(1),"sigma"=runif(1),"theta"=rnorm(J))
}''')
jagsfit = r2jags.jags(data = jags_data, inits = jags_inits,
parameters_to_save = jags_params,
n_iter = 5000,
model_file = model_file)
