sloop | Kubernetes History Visualization | Data Visualization library

In this example, there is some subtlety going on with package namespaces and S3 dispatches that I cannot understand. Can someone with deep knowledge on the subject please explain to me in simple terms, why R is dispatching as.tags.htmlwidget for this object instead of as.tags.rdeckControls?

I'm trying to build a package for data visualisation that relies heavily on ggplot2, but has some custom shortcuts for some of the day to day problems I face.

I am able to use ggplot_add function to extend the functionality of + for custom classes from scripts, however when I add these scripts to a package, ggplot_add no longer works.

Below I paste a minrep, to replicate first one needs to create a package (I'm using RStudio), that I've called SOExa. That project contains the following files:

.Rbuildignore

I noticed that the following functions in R have two slightly different classifications:

Trying to level up my Elixir understanding by doing algo/leetCode style problems using Elixir.

As I'm a relatively new programmer (around a year in) and was trained on traditionally OOP languages like Ruby and JS, it's still somewhat hard for me to wrap my head around doing algo questions in a functional paradigm, though I felt I understood the Udemy course I took on Elixir/Phoenix.

I wrote a solution to the LeetCode "valid anagram" problem using Elixir and Repl and wanted to see if people had any ideas for improving/understanding the problem or if there was a best approach way of thinking for this problem.

For an answer, I'd take a code review, a book recommendation or even just suggestions of what I could do differently.

Thank you for your time and hope this (my first question on this site) is clear.

When I run the following code in the console vs in the R markdown document, I see that the different methods are being dispatched. Is this a bug, or does the way that the code is run affect method dispatch?

I am writing a package for my use. I created objects of class marco, say.

Then I wrote some methods, like print.marco, plot.marco, etc, which I would like to be applied with print(obj) where class(obj) = "marco". In the NAMESPACE file (created with roxygen2::document()), these functions are simply exported as such and not as S3methodand are not recognized as such by sloop::is_s3_method.

I searched the internet and I can't find an answer or clear example. Following In Hadley Wickham's R packages in my R script I simply document the functions adding #' @export print.marco, etc.

A minimal example

I fetched data from one open API. And from that API I want to show image on my browser. But the problem is inside Images array there are 3 images URL. After using arrays' map method i called the first object [0] but it did not work. I am using React js is my Front-end app.

This is my React js component.
