Hello, I have a list in which each element is a list. I want to create a matrix indexed by the two indices of the list. I have been using do.call, but I am not getting what I want. Let me show you: > l.intercepts #the list that nests another list $`1995` $`1995`$`31` (Intercept) 25.37164 $`1995`$`33` (Intercept) 26.66755 $`2006` $`2006`$`31` (Intercept) 25.86621 $`2006`$`33`

Dear All: I need advice about efficient looping/vectorization. I am trying to bootstrap a regression model with one lag of the dependent variable in the RHS. Specifically, let error^b_(t) be the bootstrapped error of the regression y_(t) = gamma y_(t-1) + beta x +error_(t) at time (t), y_(t) is the original dependent variable, and y^b_(t) the bootstraped y_(t) using parameter estimates gamma and

Dear Users, I already posted this question: it either went unnoticed, or it is to basic (if this is so, please sent me a hint). I would like to know if there is a way to add a common legend to an arrangement of plots. In the example below, I get four plots in my device. each one has a density for 1995 and one for 2006. I have found that using legend or smartlegend I can add a legend to each plot,
