I''m considering using arping to ping the upstream gateway. I think this will work just fine. Howev...

Hi, I'm trying to estimate the parameters of a state space model of the following form measurement eq: z_t = a + b*y_t + eps_t transition eq y_t+h = (I -exp(-hL))theta + exp(-hL)y_t+ eta_{t+h}. The problem is that the distribution of the innovations of the transition equation depend on the previous value of the state variable. To be exact: y_t|y_{t-1} ~N(mu, Q_t) where Q is a diagonal

Hello, world! Sorry to subscribe to the list only to immediately ask a question, but this one''s got me scratching my head and I can''t find the answer in the archives, the HOWTO, or on the web. Maybe I''m just asking the wrong question. Anyway, our Internet gateway is a Linux box. We''ve got two Internet feeds, a fast one from a crummy provider, and a

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.
