Saikat DebRoy and I have been working on an R package that, among other things, will read SAS data libraries in the XPORT format. Even though a SAS data set is of a fairly simple structure, it is a challenge to write code to read the libraries "properly". In fact, I am beginning to think that file format is not well-defined. Here is the situation: - a SAS data set is a table.

Even though the FDA has no policies at all that limit our choices of statistical software, there is one defacto standard in place: reliance of the SAS transport file format for data submission (even though this format is deficient for this purpose, e.g., it does not even document value labels or units of measurement in a self-contained way). Because of the widespread use of SAS transport files in

Hi I'm trying to read SAS-data on VAX/VMS to Windows R using foreign pakage read.xport and experience some problems. Following lines are used in SAS to create XPORT file LIBNAME a ''xxx; LIBNAME b XPORT ''; PROC COPY IN=a OUT=b; RUN; and I succeed in getting file that looks like correct xport file.However when typing in R following

A colleague pointed out that the United States Food and Drug Administration (FDA) has adopted a transport format defined by SAS Institute as a standard for electronic submissions of data. As a result, this format has been openly documented. The URL for the documentation on the format is http://ftp.sas.com/techsup/download/technote/ts140.html Information on the FDA standards for

I see in the archives significant discussion about SAS, CDISC formats etc. for FDA, but no direct suggestion of adding a write.xport method to the foreign package. Are there significant barriers to doing so? [[alternative HTML version deleted]]

Full_Name: Ruskin Chow Version: R 2.0.1 OS: Windows 2000 Submission from: (NULL) (203.169.154.66) Data imported from SAS using read.xport() in package foreign are converted to <NA> when the SAS data field consists of character strings that are only one character long. This is apparently a previously reported bug and perhaps fixed in some platform other than Windows (rw2001).Some

I have encountered a problem reading SAS transport files on both a Mac (OS X) and Linux (RedHat 9), both using R2.0.1. After loading "foreign", the command: read.xport("V1622101_050304.xpt") yields: Error in lookup.xport(file) : File not in SAS transfer format In Linux, I can "cat" the file. The first few lines are: **COMPRESSED** **COMPRESSED** **COMPRESSED**

Hi, SAS transport files created with the xport engine in SAS can be read using read.xport. However, the xport engine only works with SAS version 6, and consequently long variable names are not allowed... Can anyone tell me how to get SAS data (ver 8) into R (easily)?

Dear All, I try to read the SAS transport file in R, but it shows error. Please help!

Hi! I'm trying to start a credibility estimation study with a coule of data sets that are created for SAS. The data sets are saved as ".sas7bndx" and ".sas7bdat". I've tried reading them to R with the function 'read.xport' but this returns the error message 'Error in lookup.xport(file) : unable to open file'. Are there any other functions that one

Looked at a lot of documentation and listserv postings and still can’t solve this problem. I need to get a SAS dataset into R. I’ve converted it to an .xpt file and when I try to read it I get: > read.xport("cft2008R") Error: could not find function "read.xport" > Not sure what I’m doing wrong. I’m running SAS 9.1.3 on an UNIX box. I ftp’d the file over to my

Hi all there Can some one clarify me on this issue, features wise which is better R or SAS, leaving the commerical aspect associated with it. I suppose there are few people who have worked on both R and SAS and wish they would be able to help me in deciding on this.

Hi, I am trying to read a SAS version 9.1.3 SAS dataset into R (to preserve the SAS labels), but am unable to do so (I have read in a CSV version). I first created a transport file using the SAS code: libname ces2 'D:\CES Analysis\Data'; filename transp 'D:\CES Analysis\Data\fadata.xpt'; /* create a transport file - R cannot read file created by proc cport */ proc

I like R more than SAS. My job is doing research on clinical trial. But I was told that FDA only accepts the result from SAS. Is that true? TOO BAD. [[alternate HTML version deleted]]

I have downloaded R--no problem there. Unfortunately, I have run into a second problem. I am trying to use read.ssd and then read.xport (to get a SAS data set). I have imported the package "foreign" according to instructions ( options(CRAN="http://cran.us.r-project.org/") and install.packages("foreign") ), but when I do so and then use either read.ssd or read.xport I

Dear All, I get the following error when using either SASxport or Hmisc to read an .xpt file: > w <- read.xport("D:/consult/Trophos/dnp/base/TRO_ds_20081006.xpt") Erreur dans factor(x, f$value, f$label) : invalid labels; length 15 should be 1 or 14 > z<- sasxport.get("D:/consult/Trophos/dnp/base/TRO_ds_20081006.xpt") Erreur dans factor(x, f$value, f$label) :

Is there such a function (like sas.get for S ...) to be able to convert a SAS dataset (PC one .sd2) to a dataframe or matrix in R? thanks -- Didier G.

I am attempting to read in a SAS 9.1 data file. After starting R I change to the directory containing the sas data file and use the "dir" command to confirm that it is there. Then I run the following R-code: library(foreign) sashome <- "/Program Files/SAS/SAS 9.1" test<-read.ssd(file.path(sashome), "pcb", sascmd = file.path(sashome,

Hello, I'm trying to import a SAS file made using SAS on Unix. Currently I'm using SAS on Windows and I'm trying to import that .ssd04 file to R.
