Ok. Basically everything that SAS can do, R can do, but vice versa isnt true. using the "Anne" package just renames the functions into standardized data and proc steps for user comfort.
Once SAS user finds that R is productive , and useful and even more powerful for even less money, he can unload the "Anne" Package , and move straight away into R like "intro of R' It is also a good personal exercise for me to learn how to create R packages. Jai ho !!! Ajay You can read more on this concept idea here (note it is an idea not a package now-- and so i have posted on it) http://www.decisionstats.com/2009/03/an-r-package-only-for-sas-users/ On Tue, Mar 3, 2009 at 10:28 AM, Ajay ohri <ohri2...@gmail.com> 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... > > Regards, > > Ajay > > www.decisionstats.com- Show quoted text - > > > On Tue, Mar 3, 2009 at 9:20 AM, Greg Snow <greg.s...@imail.org> wrote: > >> This does not really address my point.
