Altair slc does not support 'proc iml' ImportDataFromR function

Question

18            call ImportDataFromR("workx.testout", "testout");

^

ERROR: The CALL routine "IMPORTDATAFROMR" is not known

/--- USE CASE ---/

proc datasets lib=workx kill;

run;quit;

libname workx "d:/wpswrkx";

data workx.test;

test=constant('pi');

run;

options set=RHOME "C:\Progra~1\R\R-4.5.2\bin\r";

proc iml;

call ExportDataSetToR("workx.test", "test");

submit / R;

   testout<-test

   print(testout)

endsubmit;

call ImportDataFromR("workx.testout", "testout");

quit;

18            call ImportDataFromR("workx.testout", "testout");

The reason I need this is the ability to wrap a macro around

'proc iml' calling R. The slc does not allow  wrapping 'proc r' in a macro?

This is the key code to wrap 'iml calling r' in  a macro. Thisstructure does not work in the slc 'proc r'.

submit / R;

source('c:/temp/r_pgm.txt',echo=TRUE)";

endsubmit;"

Would  greatly appreciate  support for creating sas datasets from proc iml 

and in post python 310.

A temporary workaround might be to create wpd datasets from R and recent Python versions?

Thanks
