I am wondering if it is possible to perform the following two basic functions with primitive R functions. I know I could write functions for either, but it seems as though they are probably built-in somewhere. 1) Fill out a vector to a desired length with missing values or zeros. So, x<-c(3,4,5) f(x,5) 3,4,5,NA,NA 2) Find the [row,col] location of a particular value in a matrix, eg

I am having trouble with the rfImpute function in the randomForest package. Here is a sample... clunk.roughfix<-na.roughfix(clunk) > > clunk.impute<-rfImpute(CONVERT~.,data=clunk) ntree OOB 1 2 300: 26.80% 3.83% 85.37% ntree OOB 1 2 300: 18.56% 5.74% 51.22% Error in randomForest.default(xf, y, ntree = ntree, ..., do.trace = ntree, : NA not

I've seen a number of issues with the loading of workspaces discussed previously, but here's another one... I simply can't load any saved workspace at all... Here's an example, starting with an empty workspace and creating a single variable "a". > a<-1:5 > save.image("a.Rdata") > rm(a) > load("a.Rdata") Error in function ()  : unused

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

useRs and developeRs- Apologies for my naivety, but I just couldn't figure out how to open an old workspace (created using R 2.3.0) using R 2.3.0 and not R 2.4.0 which is currently happening. For all I know this has always been the case, but I'm having a problem with a function that doesn't work in 2.4.0 but does work in 2.3.1 (function is in the process of being fixed). So I would

Hello. I have grown accustomed to the .Data directory in S-Plus and so when I came to R I continued that behaviour by saving my workspaces at the end of each R session. So, I have saved workspaces in various directories where I have used R just as I would have had various .Data directories where I had used S-Plus. I have seen comments on the list, most recently from Prof. Ripley that they

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

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

Hi, Is there any way to load workspaces (e.g. stuff from save.image) from the command line? I'm on Linux, and would find this very helpful. I'm guessing this functionality can be duplicated with a skillful bash script to rename the particular file to .RData (and then back once R terminates), but I'm wondering if there's a better way.

I find that if start R-2.6.0 in a workspace with no .RData file, load one of my workspaces from R-2.5.1 or earlier into R-2.6.0, and then before doing anything else type postscript(file="z.ps"), I get:: > ls() character(0) > load(url("http://www.maths.anu.edu.au/~johnm/r/test5.RData")) > postscript(file="z.ps") Error in postscript(file = "z.ps")

Quite often I save misc functions and data objects as .RData files that I can use in other sessions. Although I could 'Load Workspace" these files, most of the times I prefer attaching them. It would be really convenient to have a menu item under the File menu on the Windows R Console to allow attaching workspaces, e.g. -------------------- Attach Workspace... Load Workspace... Save

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

I'm having that problem where I am sometimes using an object that's from a previous workspace when I don't want to be doing that. I was thinking of putting rm(objects=ls()) in my first.R function But, the problem with doing this, is that it doesn't prompt you with "are you sure" and there could be very rare cases where I don't want to delete the workspace ? Is there a

What is the best way (if possible) to pass the name of a workspace file to R when it starts so it is loaded instead of .RData ? I would like to know this for Linux and windows version. For windows I would like to associate the .RData extension so doubleclicking the file starts R and loads it. Thanks -- Victor Moreno V.Moreno at ico.scs.es Servei

Hi list, Is there a easy way to compare objects in two different workspace files (i.e. .RData files) in R?? I can use some generic file compare softwares (e.g. BeyondCompare) to binary comparison, but when it says they're different you can't tell where the difference are from. Thanks! Tao

I'd like to develop a simple library in R in which to save my particular functions. I have read the manual on "Writing R Extensions" but it's too difficult. Someone could help me? I want only save my personal function (recorded in R-code, not in C) in "myLibrary" and I want to call it with: >library (myLibrary). After this, the functions should be available

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

Hi, I have a problem with a package I have developed in that functions do not get loaded due to older versions of the functions being in the .GlobalEnv? fetched from .Rdata files stored from previous saved workspaces. I need to be able to fix this somehow when I load the package. I do not want to mess up the search order to fix the problem. How I got myself into this mess is that I started
