How can I get the results of lm() into a list so I can loop through the results? e.g. myResults[1] <- lm(...) myResults[2] <- lm(...) myResults[3] <- lm(...) ... myResults[15] <- lm(...) myResults[16] <- lm(...) so far every attempt I've tried doesn't work throwing a "number of items to replace is not a multiple of replacement length" error or simply not working.

First make sure that myResults is a list (you probably did this, but just to be sure):> myResults <- list()Then use doubled brackets [[]]:> myResults[[1]] <- lm(...)Etc.

My guess is that you did not define the list correcly before making any assignments to it. Try something like> myResults <- vector("list", 16)and then your code> myResults[1] <- lm(...) > myResults[2] <- lm(...) > myResults[3] <- lm(...)...> myResults[15] <- lm(...) > myResults[16] <- lm(...)HTH, Giovanni> Date: Tue, 21 Jul 2009 11:27:52 -0500 > From: Idgarad <idgarad at gmail.com> > Sender: r-help-bounces at r-project.org > Precedence: list > DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma; > DomainKey-Signature: a=rsa-sha1; c=nofws; d=gmail.com; s=gamma; > > How can I get the results of lm() into a list so I can loop through the results? > > e.g. > > myResults[1] <- lm(...) > myResults[2] <- lm(...) > myResults[3] <- lm(...) > ... > myResults[15] <- lm(...) > myResults[16] <- lm(...) > > so far every attempt I've tried doesn't work throwing a "number of > items to replace is not a multiple of replacement length" error or > simply not working. > > ______________________________________________ > R-help at r-project.org mailing list > 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. > >-- Giovanni Petris <GPetris at uark.edu> Associate Professor Department of Mathematical Sciences University of Arkansas - Fayetteville, AR 72701 Ph: (479) 575-6324, 575-8630 (fax) http://definetti.uark.edu/~gpetris/
