Calling R Language Statement from SAS IML

UrvishShah — Fri, 26 Feb 2016 16:47:53 GMT

Hi All,

I am trying to call R language statement by using "PROC IML" in Base SAS 9.4...

I have SAS IML Studio 14.1, SAS/IML 14.1 and R 3.2.2/R 3.2.3 and also set the following in configration file of SAS...

-RLANG
-SET R_HOME "<C:\Program Files\R\R-3.2.2>"

Still I am getting following error in Base SAS...

ERROR: SAS could not initialize the R language interface.
ERROR: An installed version of R could not be found.

When I tried to call R language statement in SAS IML Studio, it works fine...

I need to call R from Base SAS Proc IML not from SAS IML Studio...

Thanks in Advance!!!!!

-Urvish

You almost never have to define R_HOME if you install R in a standard place. In fact, I think the SAS/IML documentation for calling R. doesn't even mention it.

Remove the refernce to R_HOME. If you need it, I believe that the correct syntax does not contain the angle brackets; just use "C:\Program Files\R\R-3.2.2"

Hi Rick,

Thanks for the quick response...I just removed it and it is working fine now...Do you think we can use SAS Language within the R Interface...I whould like to use SAS Language within SUBMIT and ENDSUBMIT block while using R language...

Thanks again!!!

Yes, you can call SAS procedures and R functions in the same program. That is Advantage #4 on the list of "Twelve advantages to calling R from the SAS/IML language"
