I have a very simple Konva-react app (I've taken it right out of the docs) and it doesn't work (doesn't display the image) displaying two warnings:

1. Warning: is using incorrect casing. Use PascalCase for React components, or lowercase for HTML elements.
2. Warning: The tag is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter. My Canvas component:

I have code that includes several initial checks of different parameter values. The code is part of a larger project involving several R scripts as well as calls from other environments. If a parameter value does not pass one of the checks, I want to

1. Generate a customizable result code
2. Skip the remaining code (which is not going to work anyhow if the parameters are wrong)
3. Create a log entry with the line where the error was thrown (which tells me which test was not passed by the parameters)
4. Print my customizable result code to the console (without a more detailed explanation / trace back from the error)

Otherwise, the remaining code should be run. If there are other errors (not thrown by me), I also need an error handling resulting in a customizable general result code (signalling that there was an error, but that it was not one thrown by me) and a more detailled log.

The result codes are part of the communication with a larger environment and just distinguishes between wrong parameter values (i.e., errors thrown by me) and other internal problems (that might occur later in the script).

I would like to use tryCatchLog because it allows me to log a detailed traceback including the script name (I am sourcing my own code) and the line number. I have not figured out, however, how to generate my own error code (currently I am doing this via the base function stop()) and pass this along using tryCatchLog (while also writing a log).

Example

In the following example, my parameter_check() throws an error via stop() with my result code "400". Using tryCatchLog I can catch the error and get a detailed error message including a traceback. However, I want to seperate my own error code (just "400"), which should be printed to the console, and a more detailed error message, which should go to a log file.

I am stuck and need help finishing this fetch request. I need a function to check if the movie (a single object) in the request has previously been rated by the user.

The ratings are in the ratedMovies array. If the movie was rated I need the userRating property with it's value to be added to the response. If it has not been rated, I need the userRating value to be null

I have a tibble (data.frame) that I need to apply a number of type updates to. I have a readr::col_spec object that describes the desired types, but since the data does not originate as a csv file, I cannot use read_csv(..., col_types=cspec) to apply the changes to the specified columns.

Since col_spec is a data structure designed exactly to specify desired data types, I would nevertheless to use it directly as an input to a function that applies the changes for me, rather than writing a long custom script to apply the different columns. See the following example:

I am looking for a RegEx to match all lines that have a specific quantity of delimiters or less.

For example, I have a large file with - as the delimiter

I was wondering if there was a way to sort my mongodb results by the index of the search keyword.
For example if I search the db by {name: da} i'll get back results like [{name: "yoda"}, {name: "david"}, {name: "soda"}, {name: "daniel"}]. But I would want the order to be something like this [{name: "david"}, {name: "daniel"}, {name: "yoda"}, {name: "soda"}]. I know that I can sort the results after I find them like this:

const re = new RegExp(keyword, "i");
results.sort((a, b) => a.name.search(re) - b.name.search(re)

But I also wanted to limit the amount of documents I get back from the database. I looked at the textScore metadata in the mongodb docs, but I have no clue if its useful in my case.

I'm using chez 9.5.4 on a Mac.

The following code:

Context: I need to use factor order to make arrange diplays a table in a certain way. I.e I want to get a "Total" line at the end of each group.

Problem: using fct_relevel I acheive the expected output only within the first group.

Repex:

In the code below I've created a button component with the help of React. Since React allows you to create reusable components, I wanted to be able to create a button that could contain different text and be a different color. For example:
