Hi All,

I wanted to test exposing an R function. But folowing the manual in version 5.00 I can not run a test query. I have setup an R code env, R recipes work fine.

The log is quit big, the errors I get are given in the text below. When following the example for a custom python function everything goes fine,

Any thoughts?

Cheers, Longhow

    For a R function endpoint, you need the "gtools" package in the code environment

    I installed gtools, but I am getting a different error now.
