Dear All! Reading character strings containing an "umlaut" from a csv-file I find a (to me) surprising behaviour in R 2.8.0, that I did not notice in R 2.7.2. A comparison by "==" results in FALSE, while grep does find the aggreement. See the example below. The crucial line is x=="div 1-2 Ver?nderungen", with the result [1] FALSE in R 2.8.0 but [1] TRUE in R

Dear people, I have got a question concerning the underlying numerical codes when reading an SPSS file into R. I used the package foreign and when I look at a variable I get the verbal codes. I would like to know how it is possible to get the underlying numerical codes as output, which are the same as in my SPSS file. Thank you very much in advance for your help!

Dear All, after searching on CRAN I got the impression that there is no standard way in R to label values of a numerical variable. Since this would be useful for me I intend to create such an attribute, at the moment for my personal use. Still I would like to choose a name which does not conflict with names of commonly used attributes. Would value.labels or vallabs create conflicts? The

Hello! A problem with special characters seemed to me to be a bug. I sent a mail to R-windows at r-project.org concerning the problem (see below). How can I find out, if this is considered as a bug or an error of myself? Which part of FAQs or documentation did I miss to find the answer? thanks in advance Heinz T??chler -------------------- copy of abovementioned mail ---------- to: R-windows

Hi, after updating to foreign version 0.8-32, I experienced the following error when I tried to load a SPSS file: Fehler in inherits(x, "factor") : objekt "cp" nicht gefunden Zus?tzlich: Warning message: In read.spss("***l.sav", use.value.labels = TRUE, to.data.frame = TRUE) : ***.sav: File-indicated character representation code (1252) looks like a Windows

Hello, does anyone have experience with reading SPSS Version 15.0 files into R (version 2.4.1, WinXP)? I have long been sucessfully reading SPSS files with read.spss from the wonderful foreign package, but somehow after upgrading from SPSS14 to SPSS15 I seem to have problems. Trying a simple example, where test.sav is a SPSS 15.0 data file consisting of x1=c(1,2,3) and

I'm using Fedora Core 4, R-2.2. The basic question is: can one recover the numerical values used in SPSS after importing data into R with read.spss from the foreign library? Here's why I ask. My colleague sent an SPSS data set. I must replicate some results she calculated in SPSS and one problem is that the numbers used in SPSS for variable values are not easily recovered in R. I'm

Hello, it seems that the main results of survival analysis with package survival are shown only as side effects of the print method. If I compute e.g. a Kaplan-Meier estimate by > km.survdur<-survfit(s.survdur) then I can simply print the results by > km.survdur Call: survfit(formula = s.survdur) n events median 0.95LCL 0.95UCL 100.0 58.0 46.8 41.0 79.3 Is

Dear All, Assume I have a data.frame that contains also factors and I would like to get another data.frame containing the factors as numeric vectors, to apply functions like sapply(..., median) on them. I read the warning concerning as.numeric or unclass, but in my case this makes sense, because the factor levels are properly ordered. I can do it, if I write for each single column

Dear All, where can I find information about how to write an assigment form of a function? For curiosity I tried to write a different form of the levels()-function, since the original method for factor deletes all other attributes of a factor. Of course, the simple method would be to use instead of levels(x) <- newlevels, attr(x, 'levels') <- newlevels. I tried the following: ##

Hi, It works for me to import spss datasets via library(foreign) with read.spss or via library Hmisc by (spss.get). But no matter which way I do import the data, user-defined missings from Spss are always lost. (it makes no difference if there are a single value, a range, or any combination of them. They are always ignored). Is there any way in R to find out if any value was user-defined missing

Dear All! For descriptive purposes I would like to add attributes to objects. These attributes should be kept, even if by indexing only part of the object is used. I noted that some attributes like levels and class of a factor exist also after indexing, while others, like comment or label vanish. Is there a way to make an arbitrary attribute to be kept after indexing? This would be especially

I encountered something strange with read.spss (package foreign, version 0.7 with R2.0.0 and version 0.8 with R2.0.1 beta, windows XP) I made a test file test.sav with SPSS version 11.5.1 containing only one numeric variable, with a value label for one value not occuring in the file. According to ?read.spss this should result in a factor, but it results in all NA. Using the argument

[I tried to send this message privately, but the return address bounced.] I think this has been fixed in R-patched, but I doubt if the fix has been tested in Win98. Could you please download a copy from <http://cran.r-project.org/bin/windows/base/rpatched.html> and confirm that it has been fixed?

Dear R-users, I am using R version 2.10.1 and package foreign version 0.8-39 under windows. When reading .sav-Files (PASW Statistics 18.0.1) containing string variables, these are automatically converted to factors when using option "to.data.frame = TRUE" (see example below). It's clear to me why this happens (the default behaviour of a call to as.data.frame). But this is not

Hello guys I am new to this list and for R too. I am wondering if there is a patch for the SPSS reading code on the foreign package, in order to be able to read long variable names. Right now read.spss() just trunc the names to 8 characters. Or if someone could help me on other way: I have to process everyday a lot of SPSS Syntax Files and Dat files that come from one system that can only export

Hello, still I have difficulties with variable names in functions. I know the famous example form help for deparse/substitute but I will give a simpler one to explain my problem. I know from Reid Huntsinger (Tue, 8 Feb 2005 12:39:32 -0500) that: "Semantically, R is pass-by-value, so you don't really have the names, just the values. In implementation, though, R *does* pass names, in part

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.
