We want to sum many vectors and numbers together as a vector if there is at least one vector in the arguments. For example, 1 + c(2,3) = c(3,4). Since we are not sure arguments to sum, we are using sum function: sum(v1,v2,...,n1,n2,..). The problem is that sum returns the sum of all the values present in its arguments: sum(1,c(2,3))=6 sum(1,2,3)=6 We do not want to turn sum(v1,v2,...,n1,n2,..) to

Dear R Helpers, I am trying to do calculations on multiple data frames and do not want to create a list of them to go through each one. I know that lists have many wonderful advantages, but I believe the better thing is to work df by df for my particular situation. For background, I have already received some wonderful help on how to handle some situations, such as removing columns:

Dear fellow R users, I am trying to conduct a regression analysis. I have thousands of variables. The names are V1, V2,........V2000 Is there an easy way to include these variables in the regression? my model is something like that: model<- lm(y~V1+V2+.....+V2000, data=data) Thanks so much in advance, Ozlem

Hello, I need some form of a "permutative" operation on a numeric vector x x = (v1, v2, v3, ..., vN) that produces x.r = (v1, v1+2, v1+v2+v3, ... v1+v2+...+vN) If the operation is sum() I can run x <- 5:8 m <- matrix(rep(x, length(x)), ncol=length(x)) (x.r <- rowsum(m * upper.tri(m, diag=TRUE), rep(1, length(x)))) But there's two things I don't know and kindly

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hi, Since update to 2.6.37 I can''t build openwrt on my btrfs buildroot anymore. I''m not sure if this is related to the other flush-btrfs-1 thread. plenty of diskspace is free: /dev/mapper/cruor-build 97G 68G 27G 73% /opt/build It always hangs when openwrt builds the ext4 image and runs tune2fs on it.

I implemented a Temperature model for my application. It is pretty basic, composed of a temperature, a unit and some conversion methods. In my app model I decided to store temperature values in Fahrenheit, so there is no need to remember the units between invocations. I am having a little trouble composing my app model. A little bit of my temperature class: class Temperature # Composed of

Dear LLVMers, The heating/cooling maintenance in our building has started. I peeked into the server room in which the LLVM SVN server is stored, and it's already 81 degrees Fahrenheit in there. Our IT staff will shut systems down once the temperature reaches 84 degrees Fahrenheit Again, I strongly recommend that people not make any SVN commits or Bugzilla changes until the cooling

I made my own RUnit testing convention, and I want to introduce this to one of my friends. Before that, I'd like to review my codes. The problem that I met when I tried to polish my codes is: How can I get the file path in the file??? I.e., I want to get the path to the file that I'm writing using some magic R functions. But I couldn't find any good magic. Is there any magic? So, I

So, per the discussion last week and generous donations, we have some new sound files with which to work. The sounds are located in: http://www.loligo.com/asterisk/sounds/ For those of you who just want to download the _new_ sounds, please fetch: http://www.loligo.com/asterisk/sounds/20040117.newsounds.tar All of the sounds in that tarball are also in the main ../sounds/ directory in

Is there any package for Vector Auto-regressive with exogenous variable other than fastVAR? Because it is not able to solve my problem of not taking the base in the model.

Hi All, This question may not belong here, but I asked this on the R-SIG-FINANCE list and so far have not got any reply, so was hoping someone here may help. I have a basic query about TSRV and was hoping you all can shed some light on the issue. I have 22500 records for each day. So if I take the slow frequency as 5 mins I can have 75 subgrids. An estimate of the 5-minute realized volatility
