carburetor | Graphical settings app for tractor in GTK | Router library

In the following example I have two static radio buttons representing the mtcars and iris datasets. Upon making a selection, the user is presented with a second set of buttons based on data in each dataset. For the mtcars dataset, the user can filter by selecting from the unique list of carburetors or in the case of the iris dataset, the species. Now, I require another set of buttons based on the carb/species buttons to further filter the data. Say, for the mtcars dataset the list of unique gear selections associated with the carburetor selection and for the Iris the unique set of petal lengths. Given the real world application of what I'm trying to accomplish, there is no getting away from requiring a third set of reactive radio buttons. I just have no clue how to approach the next step.

I am writing a GUI app with python and GTK (PyGobject). Here is my application class:

I'm coding a program that will print output on what is happening with parts of an internal combustion engine. I have an abstract class called CarSystemParts that all car part classes inherit from.

I have a Dictionary> that shows which classes should be affected or physically pushed by other parts. It's defined like this:

I am working on a Shiny app where the reactable package has been very useful because of the nested structure of my data. It allows me to collapse and summarize rows within a higher-level category, and only expand to reveal the 'subrows' if/when desired.

For just 1 nested level (e.g., car models within makes), the aggregation functions (unique, count etc.) from reactable work just fine out of the box. However when adding extra levels of nested-ness, things break down and even aggregators like unique present repeated values (!). I suspect this is because the subcategories are not all pooled together in a flat structure with only 1 aggregation step performed on all of them, but rather unique values remain subcategory-specific and then just get concatenated together, leading to repetition. This issue affects other aggregators too, not just unique.

I'm adding a MWE below in R, as I've been unable to fix this. Since JS is also far from being my strong suit, I've been unable to insert any JS to fix this more flexibly, as is suggested here. How can I tweak the aggregators below to get correctly displayed output (i.e., no repetition)?

My problem is that I'm trying to use multiple in tag but my core (in this case, Pandorabots) is not recognizing what I wrote. I thought the problem was the multiple set tag in the pattern tag. With just one, it works.

So here's the slice of aiml:

I try to subset data based on an ID (can be any number) and one condition. An example could be;

I have several cars with a different number of cilinders and a different number of carburetors. I want a subset for every unique value of cilinders. And in the subsets of cilinders i want again a subset for every unique value of carburetors.

What i tried so far is to subset the mtcars data by the unique number of cilinders. This worked fine and it gave me 3 subsets. I used this to do so;

I'm collaborating on a project with some people who only use SPSS although I use R. I'm trying to create a dataframe in R with variable labels and value labels for factor variables to export to SPSS. However, once I open the file in SPSS, I get the variable names but not the value names.

Does anyone has any idea how to achieve this?

Here what I've tried so far. mtcars example.

I've been trying to use plot_ly with transforms (ultimately to subset data from a dropdown menu) and a color mapping.

Following is a reproducible example based on mtcars:

If I exclude the color mapping, everything works as expected:
