Means of Monte Carlo simulated lists
If you simply want an overall average of all the values do: mean( unlist( sim.theta ) ) If you want something else, you'll have to describe what you need more clearly. -Greg

For example, after two iterations, I have something like
str(sim.theta)
List of 2 $ :List of 3 ..$ : num [1:6, 1:4] -3.67 -1.07 -2.99 -18.38 -3.26 ... ..$ : num [1:6, 1:6] -7.56 -3.14 -4.99 1.03 2.79 ... ..$ : num [1:6, 1:4] -0.506 2.802 1.879 -13.457 -3.172 ... $ :List of 3 ..$ : num [1:6, 1:4] 9.664 17.242 13.555 -0.368 16.426 ... ..$ : num [1:6, 1:6] 10.54 8.97 10.89 10.76 8.81 ... ..$ : num [1:6, 1:4] 4.40 10.58 12.00 1.00 7.71 ... Could anybody tell me what is an efficient way of computing the averages of the simulated values? Thank you in advance, Giovanni --
