Hi, I am trying to figure how to use dlm with constant terms (possibly time-dependent) added to both equations y_t = c_t + F_t\theta_t + v_t \theta_t = d_t + G_t\theta_{t-1} + w...

I use R with ESS in Emacs 21.2.1 on Windows NT. When I edit a function with C-c C-d and then try to load it back with C-c C-l, I get the following error...
