As noted on the R-project web site itself ( www.r-project.org -> Manuals -> R Data Import/Export ), it can be cumbersome to prepare messy and dirty data for analysis with the R tool itself. I've also seen at least one S programming book (one of the yellow Springer ones) that says, more briefly, the same thing. The R Data Import/Export page recommends examples using SAS, Perl, Python, and

In clinical trial data preparation and many other data situations, the statistical programmer needs to merge and re-merge multiple input files countless times. A syntax for merging files that is clear and concise is very important for the statistical programmer's productivity. Here is how Vilno does it: inlist dataset1 dataset2 dataset3 ; joinby variable1 variable2 where ( var3<=var4 ) ;

In response to those who asked for a better explanation of what the Vilno software does, here's a simple example that gives some idea of what it does. LABRESULTS is a dataset with multiple rows per patient , with lab sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and SODIUM. DEMO is a dataset with one row per patient, with demographic data. It has columns: PATIENT_ID, GENDER.

That may sound like a stupid question, but if it confuses me, I'm sure it confuses others as well. I've tried to find that information on the R mail-group info pages, can't seem to find it. Is it something obvious? To begin a brand new discussion, you do your post as an e-mail sent to r-help at stat.math.ethz.ch . As I am doing right now. How do I do an additional post that gets

I'm using R 2.8.1 on Ubuntu 8.10. I'm writing partly to ask what's wrong, partly to tell other users who search that there is a work around. The General Social Survey is a long standing series of surveys provided by NORC (National Opinion Research Center). I have downloaded some years of the survey data in SPSS format (here's the site:

Hi All, I am writing a simulation that examines the effects of species extinctions on ecological communties by sequentially removing individuals of a given species (sometimes using weighted probabilities) and replacing the lost individuals with species identities randomly sampled from the remaining individuals. Thus I use two dataframes. One contains all the individuals and their species

Hello List-Friends ;-) O.K. I am a real beginner, so please don't hurt me ;-) but im still working since a few days to get it running and google is my best friend. I also bought O'Reilly 's Samba Book and a lot of other online stuff, but AD-Samba-winbind should be too new. I use Suse 9.1 and Samba 3.0.4 as ADS Member Server. We have an W2k Advanced Server (and a M$-Admin which

Trying to open some SPSS .sav files (saved with SPSS 15) gives the following: read.spss('/data/big/unzipped_ukda/seh3767/3767SPSS_570D6A086C9A1B0636F13255F25A58C1/prgrp95.sav') Error in read.spss("/data/big/unzipped_ukda/seh3767/3767SPSS_570D6A086C9A1B0636F13255F25A58C1/prgrp95.sav"): error reading system-file header In addition: Warning message:

We are setting up a Dovecot over a pair of NFS which mirrored with DRBD +Heartbeat, under Debian Etch AMD64 with Kernel 2.6.22-5. The problem was slow header downloading rate. We had tried to use postal to inject 500 emails which are under 5KB each, but when ever we start up Mail.app, Thunderbird or even OE6, the header download rate is terrible slow. Its look like a few sec for just 1

Hello R-Helpers, I am not sure if it is a very simple question but I would like to use two (...) in a function, for example, this is a script where I would like to input the variable names (in one of the (...)) and the variances associated to those variables which are not calculated in the script because there is a specific software to calculate it (the other (...)) data <- function

Is anyone in the leadership of the R-project going to contact the New York Times and clarify that the article gave remarkably short shrift to the people who designed the user interface for R, to a large extent AT&T researchers from an earlier generation? It would be the appropriate thing to do. The R team did not develop the user interface for R, the designers of the S programming language

Saikat DebRoy is working on a revised "foreign" package (currently in the src/contrib/Devel area on CRAN) that will include the ability to read the SPSS save format. Since we don't use SPSS we don't have easy access to a sample data set and have been using PSPP (see http://pspp.stat.wisc.edu/) to generate test data. It would be more realistic to have a small, redistributable

Hola, Tengo problemas a la hora de cargar un archivo que originalmente está en SPSS. Trabajo con Fedora y uso R mediante el plugin Rgedit en gedit. Además en Fedora no tengo SPSS, sino PSPP Para cargar el archivo he probado estas dos cosas (escribo también el mensaje de error que me genera R): >library_(foreign) >read.spss("guille.sav",to.data.frame = T) Error en

I am trying to match SAS output with R. I am using Proc Npar1way with D option to get KS test statistic. ? Here X is a binary dependent variable and Y is the predicted probabilities; proc npar1way data = mydata D; class x; var y; run; When i try this in R ks.test(x, fitted(y),alternative = c("two.sided"),exact = NULL) I get very different result compared to SAS. I am new to R.

Can R support data manipulation programming that is available in the SAS datastep?  Specifically, can R support the following: -          Read multiple dataset one record at a time and compare values from each; then base on if-then logic write to multiple output files -          Load a lookup table and then process a different file; based on if-then logic, access and lookup values in the table

Hi, I have a valid SPSS .sav file (which I can open happily in SPSS v11 on Windows XP). Opening it in R2.41 on Linux we get this message :- > HSE3023 <- read.spss("HSE.sav") Error in read.spss("HSE.sav") : error reading system-file header In addition: Warning message: HSE.sav: Variable X234 indicates variable label of invalid length 256 Now variable X234 has indeed a

Since my printer problem has changed, I'm starting this new thread as it is somewhat different than the original problem. I have a Windows shared printer that shows up with 'smbclient' if I use the -U option. However, it does not show up if I use the -N option. Instead I get the error: Error returning browse list: NT_STATUS_REVISION_MISMATCH Thus I am unable to set up the printer on

Sorry if this was double posted but since I received no response last week I'm assuming this message did not get distributed. Hopefully it did this time. I have a Windows shared printer that shows up with 'smbclient' if I use the -U option. However, it does not show up if I use the -N option. Instead I get the error: Error returning browse list: NT_STATUS_REVISION_MISMATCH Thus I am
