For the current documentation for the R package SASxport see https://cran.r-project.org/web/packages/SASxport/SASxport.pdf For bugs see https://github.com/MangoTheCat/SASxport/issues There are two outstanding issues. Note R, Python and Perl can read sas7bdats WPS and SAS can create SAS datasets from R dataframes. The express verison of WPS does not limit the size of SAS datasets created from R. Evan Miller and Hadley Wickham have an experimnetal R package that can create SAS datasets. However it has acknowledged bugs which are documented and under development. It is not usable yet. I think Matt Shotwell is working on a Java API to SAS datasets? I have used StatTransfer and it works well. There is also Carolina software, which uses JDBC? I have not used it.
