Return a list
But why do this? Just leave the (preferably named) variables as list components and work with them there. 1. ?comment tells you how to add a comment attribute to the list for self documentation (what were the components? how are they related? etc.) 2. ?with shows you how to access the components of the list individually in the "usual" way. 3. ?lapply and friends shows you how to "loop" over list components . etc. Cheers, Bert Bert Gunter Genentech -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Wacek Kusnierczyk Sent: Friday, September 26, 2008 12:40 PM To: Mike Prager Cc: R help Subject: Re: [R] Return a list

I have several output variables which I give back with the list command.
test <- function {return(list(a,b,c,d,e,f,g,...))}
After the usage of the function I want to assign the variables to the
output variables.
result <- test() a <- result$a b <- result$b c <- result$c d <- result$d ... is there a more elegant way to assign these variables, without writing
them all down?
arguably ugly and risky, but simple: for (name in names(result)) assign(name, result[[name]]) (note, for this to work you actually need to name the components of the returned list: return(list(a=a,b=b,...))) vQ ______________________________________________ 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.
