I have downloaded the Umacs (Universal Markov chain sampler) and submitted the

y =c(28, 8,-3,7,-1,1,18,12),
theta =Gibbs(theta.update,theta.init),

tau =Gibbs(tau.update,tau.init),
Trace("theta[1]")

Error: could not find function "Sampler"
Is there anything else I need to download.
Looks like you didn't attach the package using library(Umacs).
Installing just gets it onto your system, you need to attach it so the
objects in it are visible.
