Model builder tutorial

[PieterjanRobbe]

Hi there,

I'm working my way through the Model builder tutorial. After launching the Shiny app in this section, I follow the instructions in the tutorial. I go to the Features tab and toggle the cases checkmark. Then, under the Model tab, I click Run, and I get this error:

Am I missing something?

Did you change any of the codes? I am unable to recreate this issue.

Hi @mnky9800n. No, I literally copy-pasted from the tutorial. Here's the model specification:

Hi @PieterjanRobbe,

I think the issue is that the variable "UtlaName" (and also MSOA11CD) is a string variable. INLA (and inlabru) does not accept them for this purpose. I suggest we no longer offer non-numeric/non-logical variables to be selected as model/exposure variables or features.

[mnky9800n]

This is true and should be taken care of by adding a bit of logic to the app
