I need to be able to run mixed data count analyses directly in R, so I installed gamlj via

- Code: Select all
`devtools::install_github("gamlj/gamlj")`

and then copy-pasted the code given by jamovi in R syntax mode, namely:

- Code: Select all
`gamlj::gamljGlmMixed(formula = mes ~ 1 + tps + gr +tps:gr+( 1 | part ),`

+ data = g,

+ modelSelection = "nb")

It outputs the error message

Error: 'OptionOutput' is not an exported object from 'namespace:jmvcore'

Google is of no help to find out what this means.

I have checked on a simpler model (one way ANOVA) that the code displayed by jamovi in syntax mode works as such, so the problem seems to come from gamlj itself.

I have R version 4.0.5.

Thank you for any ideas.
