rubble | BLE stack for embedded Rust

I am very new to R and programming in general, please forgive my forthcoming ineptitude.

I am working with a large categorical raster. Essentially, every pixel shallower than 10 meters on the Great Barrier Reef is assigned a value: 11,12,13, or 15. (Original file here). My end goal is to create a histogram showing the frequency of the "rubble" category (which is the given by the value 12) by latitude. It would look very similar to the third panel of this figure, but where they show "coral habitat" I would be showing rubble.

I thought the best way to do this would be to try to convert the original raster into a data frame where each row represents what was a pixel and there are three columns: categorical value (11,12,13, or 15), latitude, and longitude. I could then use this data frame to create any number of basic plots.

Ideally I would like to omit NAs in the process of creating this data frame because the raster is 152,505 by 112,421, but over 99% of pixels are empty (due to the shape of the Great Barrier Reef).

I can easily read in the raster and plot it using the Raster or Terra packages:

I recently started using the stars R package. I'm struggling with reassigning NA values to "Unknown". I found a potential solution here, but it doesn't seem to work on NAs. Any suggestions to fix this issue are greatly appreciated. for some reason SO doesn't like huge chunks of code without adding more information, so i'm adding some random text at the bottom.

Here's the code that I used:

Why does local -n work on array variables when the manual explicitly says it does not? Is the manual wrong? Is this relying on some sort of bash "undefined behavior?" Is the manual out-of-date? Am I missing something?

Here is the information I'm looking at from the bash manual:

Run man bash and search for local [ using the regular expression search pattern local \[. It says (emphasis added):

local [option] [name[=value] ... | - ]

For each argument, a local variable named name is created, and assigned value. The option can be any of the options accepted by declare.

(See also help local).

So, the options that can be passed to the bash local built-in command are the same as those of declare. Let's find what options can be passed to declare:

Run man bash and search for declare [ using the regular expression search pattern declare \[. Under the -n entry there for declare [-aAfFgilnrtux] [-p] [name[=value] ...] you'll see (emphasis added):

-n Give each name the nameref attribute, making it a name reference to another variable. That other variable is defined by the value of name. All references, assignments, and attribute modifications to name, except those using or changing the -n attribute itself, are performed on the variable referenced by name's value. The nameref attribute cannot be applied to array variables.

(See also help declare).

So, despite it saying "The nameref attribute cannot be applied to array variables,", it does work just fine on array variables!

To prove that, here is a demo of it working fine for regular bash arrays:

on javascript im coding a scraper for my and for my search is in json and i wanna seprate each column that have value and data but i tried so many methods it turns out like this

Here is code to read the data out of the tables in a SQLite database:

I am really new to vue and for this project I am using Vue, Bootstrap-vue to paginate my data teamList. Is there a way that I can change the teamList.first_name into the link so that I can use onSelect or onClick event once the user clicks on the first_name value.
