Dear List, I hope this posting is not redundant. I have several list outputs with the same components. I ran a function with three different scenarios below (e.g., scen1, scen2, and scen3,...,scenN). I would like to extract the same components and group them as a data frame. For example, pop.inf.r1 <- scen1[['pop.inf.r']] pop.inf.r2 <- scen2[['pop.inf.r']] pop.inf.r3 <- scen3[['pop.inf.r']] ... pop.inf.rN<-scenN[['pop.inf.r']] new.df <- data.frame(pop.inf.r1, pop.inf.r2, pop.inf.r3,...,pop.inf.rN)
My final output would be 'new.df'. Could you help me how I can do that efficiently? Thanks in advance, Steve P.S.: Below are some examples of summary outputs. > summary(scen1) Length Class Mode aql 1 -none- numeric rql 1 -none- numeric alpha 1 -none- numeric beta 1 -none- numeric n.sim 1 -none- numeric N 1 -none- numeric n.sample 1 -none- numeric n.acc 1 -none- numeric lot.inf.r 1 -none- numeric pop.inf.n 2000 -none- list pop.inf.r 2000 -none- list pop.decision.t1 2000 -none- list pop.decision.t2 2000 -none- list sp.inf.n 2000 -none- list sp.inf.r 2000 -none- list sp.decision 2000 -none- list > summary(scen2) Length Class Mode aql 1 -none- numeric rql 1 -none- numeric alpha 1 -none- numeric beta 1 -none- numeric n.sim 1 -none- numeric N 1 -none- numeric n.sample 1 -none- numeric n.acc 1 -none- numeric lot.inf.r 1 -none- numeric pop.inf.n 2000 -none- list pop.inf.r 2000 -none- list pop.decision.t1 2000 -none- list pop.decision.t2 2000 -none- list sp.inf.n 2000 -none- list sp.inf.r 2000 -none- list sp.decision 2000 -none- list > summary(scen3) Length Class Mode aql 1 -none- numeric rql 1 -none- numeric alpha 1 -none- numeric beta 1 -none- numeric n.sim 1 -none- numeric N 1 -none- numeric n.sample 1 -none- numeric n.acc 1 -none- numeric lot.inf.r 1 -none- numeric pop.inf.n 2000 -none- list pop.inf.r 2000 -none- list pop.decision.t1 2000 -none- list pop.decision.t2 2000 -none- list sp.inf.n 2000 -none- list sp.inf.r 2000 -none- list sp.decision 2000 -none- list [[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.
