...quite a while for me to modify the bwplot code to get what I want and create a new graph type, assuming I could get it to work at all. Does anyone know of an easier way to get what I want, with and example? Lattice, grid, base, whatever, I don't especially care what tools I need to use. My only constrante is that I feed it the values required as a dataframe rather than calculate it on the fly so if we change our minds about UCL method or percentiles there is no problem.

...[t-p] + e[t] + b[1]e[t-1] + ... + b[q]e[t-q] but in my recent data model, i met a problem. In the ARMA model, p and q are fixed, but there are some constraints in the parameters a[i] and b[j], such as for some i (i<p), a[i]=0. my problem is how to get these parameters' estimation for these constrants with arima() function? or i need to write functions to realize it.

is it correct that even if the database doesn''t support or tables were not configured for Foreign Keys and / constrants , that you can still manage the relations using Rails, using model methods like, "belong_to", "has_one", and "has_many"?
