[R] help on data frame and matrix
Hey, I am given a data frame, which actually contains a matrix. But I need to convert the data frame into a matrix so that I can use the matrix operators. Can anybody help me out? Thanks a lot.

[R] help on sampling from Dirichlet process
Hey, I have a question on Dirichlet process. I am using a Dirichlet process as a prior. So I end up with a mixture distribution with a continuous component and a random number of discrete components at some mass-points. I tried some algorithms, but it's too too inefficient. Anyone know some efficient algorithm? Any easy-to-read paper or some templates? Thanks a lot. I am so frustrated.
