vtree | A realtime tree diffing algorithm | Frontend Framework library

I want to create a graph from my recursive JSON file. My JSON data is given below.

I need to implement a figure caption in a plot that is generated by the vtree package in R markdown. I learned that this is a htmlwidget and figure captions should now be possible for htmlwidgets used in R markdown with install.packages('webshot') and webshot::install_phantomjs() (reference: https://bookdown.org/yihui/bookdown/html-widgets.html#ref-R-DT. But days after I am not really any step further. I did not find any example (show case) for this issue (fig.cap for htmlwidgets in R markdown in the net) so my hope is that someone out there can give me some help! In my iris dataset example, in Fig. 1 the caption is not working in contrast to Fig. 2.

my iris set example RMD file:

According to the post How to display scatter plot with R Packages:svgPanZoom? I tried to replicate a zoomable plot in R shiny. Can someone help me with my code? Why can't I reproduce this code?

How can I use vtree package in shiny? The desired plot is not appearing when trying to render it from serverside. My code:

1. How do I resolve foo3

2. How can I resolve the object tree without async/await with only plain Promise (without depending on regenerator-runtime)

I'm trying to work with a datatype that represents expressions in a sort of universal algebra context. The usual way to express this in (pen and paper) maths is that you have a set of function symbols, F, together with an arity function. An expression is a tree where each node is labelled with a function symbol and it has as many children as its arity. In this particular example, I've also got a set of atomic variables that get injected explicitly as terms.

It's pretty clear how to write this down with Coq (I've got a snippet of code at the bottom), but I'd like to prove some sort of decidability result. I've managed to prove decidability for vectors ("If I have decidability on A, then I can get decidability on VectorDef.t A n"), but I can't work out how to do the same for my tree type.

I tried doing an explicit recursion over the structure of a tree, but I ended up needing to call out to my "decidable vector" function, which doesn't get past the termination checker. This is reasonable, since the vector function expects to be given a discriminator for arbitrary elements of its underlying type and this obviously doesn't bottom out!

I can't work out how to tell Coq that (by induction) I have decidability for some terms, and these are the only terms that appear in the vectors in question. Is there a standard trick for doing this sort of thing?

Below, the data types in question:

While playing around with Vanillatree.js I stumbled onto event.details and thought of the following:

If you want the selection from the tree to populate a textarea, you could use something like the code below, but what if you want to use something like labelor name instead of id?

I'm experimenting with drag-and-drop using cyclejs in a codepen. The standard drag methods supported by HTML 5 don't seem to support constraints on the movement of the dragged object so I went with standard mousedown/mousemove/mouseup. It works, but not consistently. The combine() operation doesn't seem to trigger even when the debug() calls show that mousedown and mousemove events have been received and sometimes the mouseup is missed. Perhaps my understanding of the operation is incomplete or incorrect. A direct link to the codepen is provided at the bottom of this post. Any help appreciated!

I have a set of XML files that I want to merge together. There's the master XML document which is a full ISO 19139 XML document, and two other XML files that may contain elements. I need to extract any of these elements from the fragment files and add to the master. There are hundreds of these sets of files, so I need to do some matching to make sure I'm combining the right set of data.

A fragment XML file might look like:
