FT | Example implementations of money-like tokens | Cryptocurrency library

Took my laptop out of house for a couple of days, didn't even get to turn it on during that time. Came back, ready to keep fiddling with my project but the page stopped working all of a sudden. I started getting ERR_ADDRESS_UNREACHABLE in the browser.

I've uninstalled homestead box, vagrant, virtualbox, with restart after each, re installed everything, same issue.

I can not ping the 192.168.10.10 address but I can SSH into the box no problem.

Running MacOS Big Sur, VirtualBox 6.1, Vagrant 2.2.18 and whatever the latest homestead version is. Really about quit programming altogether, this is super frustrating. I'd really appreciate any help. Thank you

This is the next step in my attempt to build a user-friendly transition matrix in R, a follow-on to post How to add a vertical line to the first column header in a data table?.

Running the MWE code at the bottom generates the transition table shown in the image below (with my comments overlaying). I'm trying to merge the top 2 cells (rows) in the left-most column and vertically-center the column header "to_state". Any suggestions for doing this? Using DT for table rendering if possible.

Please note that in the fuller code this MWE derives from, the table expands/contracts dynamically depending on the number of unique states detected in the underlying data.

I found good potential guidance in Shiny: Merge cells in DT::datatable, but it turns out in that case row cells in the body of the table (not header) are being merged so it is not applicable to my case.

I am not familiar with HTML, CSS. However, there are nice guidelines on-line for formatting HTML tables, including combined column/row mergers. See https://www.brainbell.com/tutorials/HTML_and_CSS/Combining_colspan_And_rowspan.htm, and https://www.w3schools.com/html/html_table_colspan_rowspan.asp. Makes me wonder if a better solution is to ditch my current DT/html combo and instead do the table completely in html where it seems there is more guidance for the rookie like me.

Here is the MWE code:

This is the next step in my attempt to build a user-friendly transition matrix in R, a follow-on to post How to add a vertical line to the first column header in a data table?. I have been spoiled by the ease of drafting eye-friendly tables in Excel and have been struggling with this in R Shiny.

Running the MWE code at the bottom generates the transition table shown on the left side of the image below (with my comments overlaying). Expressing my question in Excel-speak, I'm trying to merge the top 2 cells (rows) in the left-most column (call them cells A1 and A2), eliminate the small bit of line just above "to_state" (cell A2)(item #1 in the image), eliminate that first column's header "to_state" (in cell A2)(item #2 in the image), and into that merged column header space insert an object similar to the object hovering over the "From" columns to the right, that states "To state where end period = x", where x is the value of object transTo() (item #3 in the image). Any suggestions for doing this? Using DT for the table rendering if possible.

I'm open to any other suggestion for drafting a user-friendly, understandable state transition matrix that delineates to/from columns/rows and reactively shows the to/from periods.

Post Shiny: Merge cells in DT::datatable seems promising but it addresses merging rows in the body of the table and not header rows.

Please note that in the fuller code, the table dynamically contracts/expands based on the number of unique states detected in the underlying data. States can range from 2 to 12.

MWE code:

I would like to add a vertical line to a DT table column header. There is guidance for adding this line in post How can I add a vertical line to a datatable?, but it applies to a static table where columns are manually set whereas in my MWE code (at bottom), the columns are set using the lapply() function in a reactive setting. So I'm having trouble using this guidance in my particular circumstances.

Any suggestions for adding a vertical line to the right of the left-most column header labeled "to_state"? As shown in this image which shows a portion of the output window when running the MWE code:

Please note that in the fuller code this MWE derives from, the table expands/contracts dynamically depending on the number of unique states detected in the underlying data. Therefore I can't use a static table set up like in the referenced related post above.

Once this is resolved, I'll have several additional questions as I struggle to make a transition table readily understandable for users (such as change the "to_state" left-most column header to "To end Period = [xxx]", but that will be addressed in another post). I'm tackling this formatting issue incrementally in baby steps.

I am very unfamiliar with HTML, CSS.

Here is the MWE code:

I wrote a little script that has Neural Network approximate polynomial, and plots the result every epoch, but the problem is that I want that every iteration the new plot will overwrite the previous plot, so I can see how it changes over training.

I searched around the web and found that I need to use either ion() or isinteractive() or clear(), but I tried them all and it still does not work.

Edit: For the sake of clarification, I am using Jupyter notebook, so I want it to work on this platform.

Here's my code:

I have a dataset that has this structure (lots of questions asked to survey respondents) that I want to reshape from wide to long:

I try to use vlcj-javafx-demo to develop a video player, and I put the progress bar(Slider) on the StackPane over the video layer. In the beginning, it looks work well, but when I set maximum or full screen the app, it looks some components UI did not update correctly. How can I correct it?

Thanks a lot!

I am trying to use flextable to produce a table with ggplots inside cells using gg_chunk() however I keep getting an error: Error in dots[[1L]][[1L]] : object of type 'closure' is not subsettable even if I try to run the code from rmarkdown using an officeodown template.

This is the code I am using:
