Thanks to Dennis for solving my first question and also pointing me in the right direction.
To complete the thread ... there are times when I need to have different numbers of repeats for each object in the list. This can be accomplished with mapply() as follows ... > mapply(rep,x=have,c(1,1,2)) $a [1] 7 $b [1] 3 $c [1] 1 1 From: Dennis Murphy [mailto:[email protected]] Sent: Saturday, September 18, 2010 8:25 PM To: Derek Ogle Cc: R ([email protected]) Subject: Re: [R] Repeating values in a list Hi: How about > have <- list(a=7,b=3,c=1) > lapply(have, rep, 2) $a [1] 7 7 $b [1] 3 3 $c [1] 1 1 HTH, Dennis On Sat, Sep 18, 2010 at 6:19 PM, Derek Ogle <[email protected]> wrote: I have a list that looks like this ... > have <- list(a=7,b=3,c=1) > have $a [1] 7 $b [1] 3 $c [1] 1 and I want to have a simple way to change it to the following without re-typing the values ... > desire <- list(a=c(7,7),b=c(3,3),c=c(1,1)) > desire $a [1] 7 7 $b [1] 3 3 $c [1] 1 1 In other words, I need to create the list in desire from the list in have. In my "real" work the number of items in the list may be more than three and the number of times to repeat the numbers may be greater than two. Thank you in advance for any help you can offer. ______________________________________________ [email protected] 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. ______________________________________________ [email protected] 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.
