Checking the server logs I have discovered that many people that arrive at my posts on calling VB from R are, in fact, looking for the reverse. I have never done any programming calling R from VB; however, while I was looking for COM clients for R I also found information on COM servers. OmegaHat lists RDCOMServer as a package that exports S (or R) objects as COM objects in Windows. It provides examples on using VB, Python and Perl to call R code.

Another option is Thomas Baier’s R(D)COM Server, which is provided with examples in the same languages used by RDCOM Server.
