Another Mystery: sas7bdat != sd2

October 14, 2011
By

I received an email from a very inconvenienced statistician a few weeks ago. The problem was an old data file with the extension .sd2. Apparently, this is an obsolete data storage format used by past versions of SAS. A quick glance at the file contents revealed that this sd2 formatted file is incompatible with the

More sas7bdat progress

The development version of the read.sas7bdat function (in the sas7bdat package) now reads field labels and formats. In addition, errors of the type "found <x> <type> subheaders where 1 expected" are now a thing of the past. These improvements are largely due to work by Clint Cummins. The function also works on some files generated

tty Connection + sas7bdat: useR! 2011 Presentation Slides

Experimenting with a tty Connection for R I presented twice at this years useR!. The first was a regular talk on the tty connection patch for R. The talk went smoothly, despite a live demonstration using the DLP-232PC data acquisition module (datasheet). The slides for this presentation are here: shotwell-tty-useR-2011.pdf The image above is a

The code and documentation for this are here: http://github.com/biostatmatt/sas7bdat. I've recently restructured the code as an R package, and added some functionality. Look for the sas7bdat package on the CRAN. Also, the read.sas7bdat code has been ported to

Progress reading SAS sas7bdat files (natively) in R

This post describes some preliminary results from a compatibility study of the SAS sas7bdat file format. The most current results stored in a github repository here: sas7bdat The ultimate goal is a native solution to the incompatibility between open-source statistical software (e.g. R) and sas7bdat database files. Demonstration There has been significant progress in interpreting
