Re: [R] storing output data from a loop that has varying row numbers

Hi Ross, I think Joris answered your question, but to keep with your own code: To set up a list, you can use: DIST_LOOP <- list() Or, if you know the length: DIST_LOOP <- vector(mode="list", length=11) You would then fill up with (in your for loop): DIST_LOOP[[i]] <- SEL_HR ##Actually, what you

Take a look at ?split (and unsplit) eg: Dur <- rnorm(100) Attr1=rep(c("A","B"),each=50) Attr2=rep(c("A","B"),times=50) ap.dat <-data.frame(Attr1,Attr2,Dur) split.fact <- paste(ap.dat$Attr1,ap.dat$Attr2) ap.list <-split(ap.dat,split.fact) ap.mean <-lapply(ap.list,function(x){ x$meanDur=re

Jessica, Two further comments: 1. When you read your data, your character vectors are stored as factors; is that what you want? 2. You may be better off using a list. -Peter Ehlers On 2010-06-01 7:47, Sarah Goslee wrote: On Tue, Jun 1, 2010 at 5:04 AM, Jessica Queree wrote: My issue re

Re: [R] Help on aggregate method

It's easiest for us to help if you give us a reproducible example. We don't have your datasets (ap.dat), so we can't run your code below. It's easy to create sample data with the random number generators in R, or use ?dput to give us a sample of your actual data.frame. I would guess your prob

Is this what you're looking for? seal_list <- split(seal_dist,sel) out <- lapply(seal_list,function(x){ indx <- subset(x, x$DIST == 0) x$TO_ID <- indx$ID[match(x$TO, indx$TO)] return(x) }) output <- unsplit(out,sel) Cheers Joris On Tue, Jun 1, 2010 at 3:32 PM, RCulloch wrote
