generated list element names
* jim holtman <wubygzna at tznvy.pbz> [2012-11-19 13:14:05 -0500]: How about this (if you don't like writing two lines, encapsulate it in a function):
x <- list(10)
names(x) <- paste('f', 'oo', sep = '')
str(x)
List of 1 $ foo: num 10
I am sorry, how is this different from my second snippet (except that you use "x" and I use "z" and you use single quotes in paste and I use double quotes)?

How can I create lists with element names created on the fly? --8<---------------cut here---------------start------------->8---

I understand that tags in list() are not evaluated, but is there a more
elegant way than
--8<---------------cut here---------------start------------->8---
z <- list(10)
names(z) <- paste("f","oo",sep="")
z
$foo [1] 10 --8<---------------cut here---------------end--------------->8--- thanks! -- Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 http://www.childpsy.net/ http://www.memritv.org http://thereligionofpeace.com http://truepeace.org Unix roulette: `dd if=/dev/urandom of=/dev/kmem bs=1 count=1 seek=$RANDOM`
