Dear Contributors I would like to ask some help concerning the automatization process of an analysis, that sounds hard to my knowledge. I have a list of regression models. I call them models=c(ra,rb,rc,rd,re,rf,rg,rh)
I can access the output of each of them using for example, for the first ra$coefficients and i obtain (Intercept) coeff1 coeff2 age gender 0.62003033 0.00350807 -0.03817848 -0.01513533 -0.18668972 and I know that ra$coefficients[1] would give me the intercept of this model. What i need to do is to collect the coefficients of each regression in models, and calculate and place in a table, the following simple summation: ra rb rc ... intercept intercept intercept intercept+coeff1 intercept+coeff1 intercept+coeff1 intercept+coeff2 intercept+coeff2 intercept+coeff2 intercept+coeff1+coeff2 intercept+coeff1+coeff2 intercept+coeff1+coeff2 The calculations are trivial(I know how to do it in steps) but what is difficult for me is to invent a procedure that organizes the data in an efficient way. I tried some step , starting with collecting the coefficients but i think I am going the wrong way calcolati <- list() for (i in c(ra,rb,rc,rd,re,rf,rg,rh)) { calcolati[[i]] <- i$coefficients[1] } Thanks for any help you can provide. f. ---------------------------------- Francesca Pancotto Web: https://sites.google.com/site/francescapancotto/ <https://sites.google.com/site/francescapancotto/> Energie: http://www.energie.unimore.it/ <http://www.energie.unimore.it/> ---------------------------------- [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
