Dear all, This is what I'd like to do (I have an implementation using for loops, which I designed before I realised just how slow R is at executing them - this process currently takes days to run). I have a large dataframe containing corporate bond data, columns are: BondID Date (goes back 5years) Var1 Var2 Term2Maturity What I want to do is this: 1) For each bond, at each given date, look back over 1 year and append some statistics to each row ( sd(Var1), cor(Var1,Var2) over that year etc) a. It seems I might be able to use ddply for this, but I can't work out how to code...

Hi, is there a way to convert an rpart tree into ifelese statement that codes the data withi factors labeled for the tree? for e.g. if Age>50 and group=B,C then 'Age>50 and group=B,C' if Age<=50 then group=N,A then 'Age<=50 then group=N,A' data$tree<-as.factor(ifelse(Age>50 and group in (B,C), 'Age>50 and group=B,C',

Hi all, I know this isn't strictly Samba related, but I have a fileserver and want to install some VM software on it so I can build a new Samba DC on there and still keep the fileserver running. In your experience, what's the best VM to install? Are there any which wok better or worse with Samba? Does it make any difference? I'm running Ubuntu 20.04.1 Thanks!

Dear all, I'm looking for primary help at aggregating table() results and at writing a loop (if useful) My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period

Hi all, I'd like to propose the contribution of a Go frontend subproject to the LLVM project, based on the existing llgo project at https://github.com/go-llvm/llgo . As with the previous contribution of the Go bindings, I have obtained permission from all llgo contributors whose code is part of this contribution, to contribute their changes to the LLVM project and relicense their changes

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,
