Hi Ariel,

I've only see that type of error from trying to run a BASH script rather than an R script.

Are these errors being produced within LabKey via an RView or is it in R externally?

Can you provide us with a screenshot of the Engine Configuration you're using for R in LabKey?

It should look like the image as shown here under (Admin > Site > Admin Console > Views and Scripting): https://www.labkey.org/home/Documentation/wiki-page.view?name=knitr#markdown2

Regards,

Jon
