Waiting for convergence of MCMC models can take some time, therefore it may be a good idea to use better starting values. Using paste, one can quickly convert any (parameter) vector in the workspace into a R-style vector (with c()).
Here’s a function that takes any vector (for example 1:10) and turns it into c(1,2,3,4,5,6,7,8,9,10). Now it’s easy to quickly adapt starting values in your code.
Well, of course we can do the same with matrices.
