How can I extract all the code (chunks) from an RMarkdown (.Rmd) file and dump them into a plain R script?

Basically I wanted to do the complementary operation described in this question, which uses chunk options to pull out just the text (i.e. non-code) portion of the Rmd.

So concretely I would want to go from an Rmd file like the following

I have such an object that should be encoded to JSON (My Playground example)

I tried to fetch duplicates using this code

Basically I have a main scene with a list and an Add Student button. Clicking the Add Student button opens a new window in which there are two text fields, name and surname. These two are then passed to a Student object constructor that contains, among other attributes, the last and first name of the student. The new student object is now stored and I use a method addToNames that uses student.getName() and student.getSurname() to add the attributes into the list view. The issue is that it doesn't display the names in the list, and while debugging with print statements, I found out each student object overrides the previous one the way I implemented it. It got even stranger because I remember trying out simple print statement variations of implementing this, and some worked some didn't. Only example I can remember is that when I used print("lol") in my addToNames method as it is right now, It would work. I also want to store these values in a MySQL database with which I already have an established connection. However, I don't know how to do this . Here is my code

My JavaFX main scene controller class

I'm trying to generate an invoice using data from my spreadsheet, and I'm not very familiar with HTTPS requests, let alone Google's UrlFetchApp. I'm trying to convert this example code provided by the API into something that AppsScript can use. So far it just saves the website as a .html to the folder.

Context:
New to C++ here. I have a larger project where I have a classes A, B, and C.

• Class A has a field with type unordered_map.
• Class B also has fields of class C which have fields of type set.

I want to mutate the B objects in the map because I don't want the overhead associated with immutability. I have tried doing this with map.find() and map.at(), but with both methods, the mapped objects are not mutated as evidenced by the behavior of subsequent calls. I didn't try indexing with [] because class B does not have a default constructor.

1. According to the VSCode C++ documentation (but oddly not the online docs), the pair returned by find has a copy of the value object, which is wrong for obvious reasons.
2. I tried using at(), which supposedly returns a reference to the value object. This results in the same issue with find(), unfortunately.
3. I then tried making my map with values of *B, but later, these objects would go out of scope and I assume deallocated resulting in a segmentation fault.
4. So I even tried changing my map to be of type where the value is an index into a vector, which is where I found the problem to be general to containers as opposed to just maps.

I know I can do something like map.at(i) = map.at(i).funcWithSideEffects(); but I'm not ready to accept that this is the only way to do this. For a procedural language with a concept of state (i.e. not-a-fundamentally-functional language), it seems bizarre that there would be no way to mutate a value in a map or container-type field.

Long story short and minimum example:
How can I mutate objects in a container field such as a vector?
Example:

I am building a simple todo-esk feature where if a user clicks the edit icon, only that item is editable. I implement this currently with a useState hook, const [editingMemberName, setEditingMemberName] = useState(false), but when I call a function, editMemberName all instances of items show an input field. This is not the experience I am going for.

Here are some screen shots that should make this more clear:

As you can see, I have two cards, but when I click the tool icon, both input boxes are displayed.

Here is the code:

I am trying to refactor my code and in doing so, I am extracting a single item and putting it into its own component. This MemberItem component has multiple functions state that influence its rendering, however, when I start passing props, the component breaks. I am passing all of the functions, properties and state the the child component needs, but I am still unable to get it to render properly.

Learning MSTest -- trying to unit test a REST function: AccountController (which I believe will work) I want to start with Register. I can't get the Mocks setup for some reason. (Moq is installed). Also, I'm confused as to how this could possibly be of any use; if I mock all the controller inputs, I'm not going to get anything back? Your Advice?
