R and IML integration

MariaD — Thu, 23 Apr 2020 20:05:09 GMT

Hi folks,

We've just installed R 3.6.3, downloaded from CRAN project site, on our SAS Linux server (running RedHat). After the R installation was completed, we tested the R installation through R commands and works fine.

We added the RLANG command and the R_HOME on sasv9.cfg. We verified the path for R_HOME using R.home() command.

After that, we tried to validate if we could call and execute R through SAS EG using:

proc iml;
  submit/r; 
  endsubmit;
quit;

The following errors occurs:

ERROR: SAS could not initialize the R language interface.

ERROR: The R shared library could not be loaded: /usr/local/lib64/R/lib/libR.so

Any help?

Regards,

I think the issue is still in your definition of the R_HOME variable. You should use the Linux "export" command. In the past, I have successfully installed R on Linux using yum and I used the following export command:

export R_HOME=/usr/lib64/R

Will you try that?

Thanks. We installed R again using "--enable-R-shlib=yes" option on configuration.
