jamovi

Hi everyone,

I'm developing a module which adds to the frequencies-module by adding more options for exact or asymptotic methods. It builds on the functions for the binomial and multinomial tests and add more options. So I'd like to replace the existing functions (propTest2 and propTestN) with my newer versions. In the a.yaml and 0000.yaml I set all of the following parameters to be identical with parameters in base-jmv, except for `ns` which gets overwritten with my package-name when running `jmvtools::install()`
So, is there a way to replace or remove the binomial test from jmv?

Thanks in advance,
Dan

you can remove jmv altogether (navigate to C:\Program Files\jamovi XXXX\modules and delete it) but you can't easily remove individual analyses ... (i suppose you could modify the C:\Program Files\jamovi XXXX\modules\jmv\jamovi-full.yaml to remove them).

another option might be to propose the inclusion of the methods you're describing to jmv itself (we're pretty conservative about adding new methods, but you never know).

and another option is to write a module which "augments" existing analyses ... take a look at moretests ... it doesn't actually implement any analyses of it's own, but adds additional statistics to other analyses.

a drawback of this approach is that you can't add UI options ... so you can't add additional checkboxes, rather you have to piggy back of existing options. (for example, moretests adds kolmagarov smiroff (spelling?) if the user requests normality tests).

can we add aditional tables or plots as an addon module

yes ... but it's a bit of a delicate business ... you access the original analysis, so you can call it's methods, add columns to tables, etc. but you do have to be careful not to break the original analysis, and be mindful that if the original analysis changes, that can break your analysis (which in turn breaks the original analysis).

i think we had an issue where we changed the ANOVA, and people who had moretests installed complained that the ANOVA was now broken. it wasn't of course, we'd just broken the relationship between ANOVA and moretests.

so you do have to tread carefully.

my plan has been to allow addon analyses to add new 'expanders' with additional options, into the UI of existing analyses ... but never quite had the time to build such a system.

Thanks for the explanations. We're going to discuss how to proceed, probably just going to live with having the original jmv-tests still included ... The addon-idea sounds great but I can see how this might not be an immediate priority.
