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!

 

Luis Ángel.
