R package useful for electronic regulatory submissions

Metrum Institute and Random Technologies LLC are pleased to announce the availability of the SASxport package for the R programming language. Development of SASxport was motivated by a desire to interconvert R and SAS TRANSPORT (‘xport’) formats for NMTRAN data sets. In particular, the ability to write ‘xport’ files from within R helps achieve consistency with regulatory guidelines on electronic submissions. The new SASxport package provides the ability to directly read, list, and write SAS ‘xport’ files, including proper handling of custom SAS formats. (This extends existing functionality for reading and listing SAS transport files provided by the foreign package.) The SASxport package is freely available from CRAN: http://cran.r-project.org/src/contrib/Descriptions/SASxport.html . Additional distribution options and technical support are available from Random Technologies, LLC: http://random-technologies-llc.com/products/SASxport .

Hi Gregory, Tim, I am not sure whether this is a bug, feature or my error, but I created the data frame Data and used write.xport function of the SASxport package as follows: write.xport(Data,file="C:/Data/Data.xpt") When I open the resulting file using the SAS Viewer 9 (or when I read it back to R using read.xport) I see that all negative values were saved incorrectly. Since these files are needed for regulatory submission, it looks dangerous, so if anybody already used the package, check whether write.xport - read.xport combination returns the original data.
