Scenario: Here I am working away in R. I've got results that prove global warming is anthropogenic and also the solution for producing limitless carbon-neutral energy from nuclear fusion. Its been a good day. So, I want to save my work. I don't want to overwrite my current .RData, so I save it to another file: save(file="prize.RData") # just need to email this to the Nobel

I have some code that can potentially produce a huge number of large-ish R data frames, each of a different number of rows. All the data frames together will be way too big to keep in R's memory, but we'll assume a single one is manageable. It's just when there's a million of them that the machine might start to burn up. However I might, for example, want to compute some

I've just had an interesting thing happen to one of our students. He's using R 1.9.1 on Linux, and so I dont expect bugfixes, I'm just reporting this out of interest in case anyone else has had this happen. Starting R caused a seg fault shortly after "[Previously saved workspace restored]". Running "R --no-restore-data" worked fine so I suspected a corrupted

When I quit R, it says: > q() Save workspace image? [y/n/c]: and since I've probably got 3 R sessions running in however many different directories and I might have jumped around with setwd() , I forget exactly where R wants to save its workspace image. So could q() be changed to say what file it is going to save to before it does? Currently I have to hit 'c', then do

I'm often wanting to develop functions whilst manipulating data. But I don't want to end up with a .RData full of functions and data. It might be that I have functions that are re-usable but not worth sticking in a package. So I've tried to come up with a paradigm for function development that more closely follows the way Matlab and Python do it (partly inspired by a confused Matlab

Hi folks, OS - Ubuntu 10.04 On R I create a datafile named "data". I can evoke it on R with; > data On R Commander Data -> Active data set -> Select active data set -> (data) OK only one data set there "data" -> View data set I can read it -> Edit data set showing 25 rows of data. Clicking the box shows a thick border around it. But I couldn't

How do people go about synchronizing multiple workspaces on different workstations? I tend to wind up with projects spread around the various machines I work on. I find that placing the directories on a server and reading them remotely tends to slow things down. thanks, Eric -- Eric Turkheimer, PhD Department of Psychology University of Virginia PO Box 400400 Charlottesville, VA 22904-4400

After install of update snv_101b the xend daemon dosn''t start any more.

Hello. What happens in the following is that I create two simple functions, f and g, on the workspace. Then I replace g. When I then call f, it uses the old version of g. Now clearly, the circumstances for this to happen must be quite special and rare. But I'd say they're not pathological. It seems to require two things: 1) masked versions of f and g on a search position lower down the

Hi, I would love to make multiple histograms transposed one on another in order to show relation between the sets. I tried to write a function like this, but R tells me, that I cannot use add=FALSE in high-level commands. That's nice but I am supposed to do? rm(list=ls()) # what's wrong with underscore? #getwd("/home/matej/docs/skola/stat\_anal-cj3534/assign01/")

This is a simple SSA code generation 101 question. If I follow the IR code generation techniques in the Dragon book the statement x = y + z would translate into something like this in SSA/LLVM %0 = add %y, %z %x = %0 Obviously "copy instructions" like %foo = %bar are senseless in SSA since %foo and %bar are immutably fixed to the same value and there is no need for two aliases

HI sorry to be a nuisance to all!!! how can i see the code of a particular function? e.g. nnet just as an example

Hi, Say I''ve got a directory full of stale Tomcat temp files of the form: /usr/local/blackboard/apps/tomcat/work/Catalina/localhost/webapps_assessment/strts6866.tmp and I want to delete any files that haven''t changed in a week and not keep any backup. Should this get rid of them: tidy {

Can i somehow append objects to an .Rdata file? I didn't see an option for it in the save() method. dump() won't work since i have s4 objects in there.

Dear R users, My situation: (1) I have limited workspace for my work harddisk (about 10 GiB). (2) I have a lot of data files in R workspace (*.RData) which most of them > 200 MiB. For some reason I zip some of them, for instance "filename.RData (250 MiB)" to "filename.zip (3MiB)". In this work I have a lot of more space of my harddisk. Normally, If I want to use

Does anyone know a way to do the following: Save a large number of R objects to a file (like load() does) but then read back only a small named subset of them . As far as I can see, load() reads back everything. The context is: I have an application which will generate a large number of large matrices (approx 15000 matrices each of dimension 2000*30). I can generate these matrices using an

It is my understanding, the alloca memory routines are used for forcing variables to be allocated on the stack frame -- which you would want for source level debugging. When SSA registers are used, LLVM will decide what goes into registers and what will spill over to the stack frame. I want the latter. --w Wayne O.

hello all, will you plz tell me how can i convert RData files to txt,,,
