Hello Luis, It works for me. I just grabbed my installation of “default” several days ago, and copy-pasted the example from [1], and it works as expected. I started my server as this: $ mserver5 --dbpath=/tmp/test --set embedded_r=true Then in a mclient session: $ mclient Welcome to mclient, the MonetDB/SQL interactive terminal (unreleased) Database: MonetDB v11.28.0 (unreleased), 'test' Type \q to quit, \? for a list of available commands auto commit mode: on sql>CREATE FUNCTION rapi00() RETURNS TABLE (d INTEGER) LANGUAGE R { seq(1,10); }; operation successful (3.419ms) sql>SELECT d FROM rapi00() AS r WHERE d > 5; +------+ | d | +======+ | 6 | | 7 | | 8 | | 9 | | 10 | +------+ 5 tuples (1.967ms) If your problem persist, can you please let us know: - which monetdb version are you using? - how did you start your mserver5? - which monetdb client do you use? Kind regards, Jennie [1] https://www.monetdb.org/content/embedded-r-monetdb

Hi,

We are having issues when executing embedded R in a MonetDB SQL function. We have compiled and configured MonetDB accordingly, so as to be able to run embedded R; however, the simple example in the documentation fails to execute.

This is the function we have:

create function rapi00() returns table( d int ) language R { return seq(1,10); };

Having just “seq(1,10)” doesn’t make any difference either. When this function gets created, we don’t get any error; however, when we do the following:

select d from rapi00() as r where d > 5;

we get the this error:

Query failed: TypeException:user.s6_3[3]:'rapi.eval' undefined in: X_4:bat[:int] := rapi.eval(7fdb9830e210:ptr,"{\n\treturn seq(1,10);\n};":str);

We don’t know how to tackle this issue. We have followed the process from https://www.monetdb.org/content/embedded-r-monetdb. Do you have any suggestion to make this work?

Thanks!
