As a (potential) alternative solution to the problem, you may want to address R functionality over RESTful web services, using e.g. the R Service Bus. Then your Delphi clients can all make use of a single central installation of R. See http://rsb.doc.openanalytics.eu/dev/ for the technical documentation and http://rsb.doc.openanalytics.eu/dev/wsdocs/index.html for the API overview.
