That's not exactly what I meant. Right now, you can, for instance, write a transformation script that is executed when assay data is imported. These scripts can be written in any language one has configured a script engine for, such as R.

But how else can R scripts sitting on the server be triggered? I would like to be able to write R scripts, put them on the server, and be able to trigger them via some sort of call to the server through the web interface, whether there's a function in the javascript api that will do that is the question.

In the future, we'd like to be able to trigger extremely computationally intensive activities this way, which means writing scripts that are callable from the labkey server-side code that will take the data, send it to a cluster, and then import that data back into labkey when the computation is done (potentially days or weeks later).
