I think SAS Macros has capability to call R, and execute it without it being in the picture anywhere. So you can use SAS Macros in a file called R.sas
In this you can create a macro called %Describe that can call R , load Hmisc ,run the describe function Note you will need repeated use of %put in this %describe for the mapping to take place Use %INCLUDE to include that file in all SAS Programs In fact there is a 50 dollar program written by Phil Rack at www.minequest.com which does exactly that.... see more here http://www.decisionstats.com/2009/02/interview-phil-rack/ On Tue, Mar 3, 2009 at 8:53 PM, Ajay ohri <ohri2...@gmail.com> wrote: > > why didnt you call it procunivariate if that was exactly what you wanted to > do ..... > > > On Tue, Mar 3, 2009 at 7:11 PM, Frank E Harrell Jr < > f.harr...@vanderbilt.edu> wrote: > >> Ajay ohri wrote: >> >>> for an " inefficient " language , it sure has dominated the predictive >>> analytics world for 3 plus decades. >>> I referred once to intellectual jealousy between newton and liebnitz. >>> >>> i am going ahead and creating the R package called "Anne". >>> >>> It basically is meant only for SAS users who want to learn R , >>> without upsetting the schedule of the corporate users. >>> >>> Simply put , it is a wrapper on SAS language using the function >>> command...ie >>> procunivariate function in "Anne" package would call the summary function >>> and so on... >>> >> >> Go ahead and add to the confusion.
