Hi everybody, I'd like to have a list with two elements, where both elements have the same value:
z <- list(a=1, b=1) If it happens, that I've to change the value, I've to assure that I change both. This is error prone. Hence, a better way to achieve this is to define: tmp <- 1 z <- list(a=tmp, b=tmp) Now, I'm wondering if it is possible to make this more compact: z <- list(a=tmp<-1, b=tmp) Both approaches have the side effect that a variable "tmp" is created. So is there a way to achieve the same thing without having to define an additional variable? Something like z <- list(a=1, b=a) or even z <- list(a=b=1)? Both commands don't work of course, but I'm just curious whether this is possible in principle (a rather academic question I've to admit) Thanks + BR, Thorn Thaler Applied Mathematics Group Nestlé Research Center PO Box 44 CH-1000 Lausanne 26, Switzerland Phone: + 41 21 785 8220 Fax: + 41 21 785 8556 ______________________________________________ R-help@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.
